Abstract Dual-polarization weather radars typically measure the radar reflectivity at more than one polarization state for transmission and reception. Historically, dual-polarization radars have been operated at copolar and cross-polar states defined with respect to the transmit polarization states. Recently, based on the improved understanding of the propagation properties of electromagnetic waves in precipitation media, the simultaneous transmit and receive (STAR) mode has become common to simplify the hardware. In the STAR mode of operation, horizontal and vertical polarization states are transmitted simultaneously and samples of both horizontal and vertical copolar returns are obtained. A drawback of the current implementation of STAR mode is its inability to measure parameters obtained from cross-polar signals such as linear depolarization ratio (LDR). In this paper, a technique to obtain cross-polar signals with STAR mode waveform is presented. In this technique, the horizontally and vertically polarized transmit waveforms are coded with orthogonal phase sequences. The performance of the phase-coded waveform is determined by the properties of the phase codes. This orthogonal phase coding technique is implemented in the Colorado State University–University of Chicago–Illinois State Water Survey (CSU–CHILL) radar. This paper outlines the methodology and presents the performance of the cross-polar and copolar parameter estimation based on the simulation as well as data collected from the CSU–CHILL radar.

This paper addresses the problem of automatic quality inspection in assembly processes by discussing the design of a computer vision system realized by means of a heterogeneous multiprocessor system-on-chip. Such an approach was applied to a real catalytic converter assembly process, to detect planar, translational, and rotational shifts of the flanges welded on the central body. The manufacturing line imposed tight time and room constraints. The image processing method and the features extraction algorithm, based on a specific geometrical model, are described and validated. The algorithm was developed to be highly modular, thus suitable to be implemented by adopting a hardware–software co-design strategy. The most timing consuming computational steps were identified and then implemented by dedicated hardware accelerators. The entire system was implemented on a Xilinx Zynq heterogeneous system-on-chip by using a hardware–software (HW–SW) co-design approach. The system is able to detect planar and rotational shifts of welded flanges, with respect to the ideal positions, with a maximum error lower than one millimeter and one sexagesimal degree, respectively. Remarkably, the proposed HW–SW approach achieves a 23× speed-up compared to the pure software solution running on the Zynq embedded processing system. Therefore, it allows an in-line automatic quality inspection to be performed without affecting the production time of the existing manufacturing process.

In co-operation with an Austrian small sized company, the Institute for Handling Devices and Robotics at the Vienna University of Technology started a project with the goal to reduce the time necessary for planning, programming and set-up of robot equipped manufacturing cells. In this contribution a modular, object-oriented control system for robotized cells is presented. This system ‘C_CTRL' is responsible for all necessary tasks, like sequencing, supervising, controlling of basic functions, error handling, and recording of statistic data. The control system is ‘self-generating' during program start-up – using hardware information from a simple ASCII configuration file. Regardless which and how many components used in a particular cell, there is no additional programming effort for generation of the entire control software.

Abstract Released heat from production process contributes the largest proportion of cooling load in computer hardware manufacturing industry. According to traditional design practice, chiller plant produces chilled water at a temperature of 7°C to treat the entire load from the production process and from the comfort air-conditioning in buildings. However, the heat from the process is solely the sensible component where high-temperature chilled water (e.g., 15°C) can be used for the heat removal, the chillers equipped with low temperature-lift technology thus offer a great opportunity to improve the plant’s cooling performance. Under the critical global warming situation and the need of decarbonizing industry, this paper investigated the energy saving and CO2 emission mitigation potential of the low-lift technology by which the chiller plant of high-temperature chilled water (15°C) is dedicated for the production process cooling, and the traditional chiller plant of the low-temperature chilled water is used to serve the building air-conditioning. The study site was a large factory of computer hardware manufacturing in Thailand. Through detailed energy auditing, the cooling load profile of the production process was established, and it was used to design the low-lift chiller plant. The annual simulation results showed that in our study case the low-lift chiller plant together with variable motor speed control had 31.6% higher cooling performance than the traditional chiller plant. The plant could reduce the energy consumption by 5,550 MWhelec/year. As the CO2 emission of the grid power in Thailand was 0.47 kgCO2/kWh in 2023 and it was expected to reduce to 0.35 kgCO2/kWh in 2050, the CO2 emissions from implementing the low-lift cooling could be reduced by 49,400 TonCO2 over a course of the 20-year project lifetime. The study results encouraged the low-lift cooling technology as a practical energy efficiency measure in computer hardware manufacturing industry. To our knowledge, while past research focused on the low-lift cooling in building air-conditioning, the study was the first potential assessment project of the low-lift cooling as a deep decarbonization technology for the computer hardware manufacturing industry in Thailand.

For complex systems, it is not easy to obtain optimal designs for the hardware architecture and control configurations. Every design aspect influences the final performance, and often the interactions of the different components cannot be clearly determined in advance. In this work, a novel co-design optimization method was applied that allows the optimal placement and selection of actuators and sensors to be performed simultaneously with the determination of the control architecture and associated controller tuning parameters. This novel co-design method was applied to a state-space model of a downscaled active car suspension laboratory setup. This setup mimics a car driving over a specific road surface while active components in the suspension have to increase the driver’s comfort by counteracting unwanted vibrations. The result of this co-design optimization methodology is a Pareto front that graphically represents the trade-off between the maximum performance and the total implementation cost; the co-design results were validated with measurements of the physical active car suspension setup. The obtained controller tuning parameters are compared herein with existing controller tuning methods to demonstrate that the co-design method is able to determine optimal controller tuning parameters.

According to the traditional design method, in order to manufacture a mechatronic system, from the initial idea, the designer designs the mechanical system by CAD (Computer-Aided-Design), this system is then fabricated, finally, the system will be tested on the working condition. If the system does not work properly, the design of the system will be changed, and hardware is re-manufactured. This method is more time-consuming and cost for repairing and manufacturing hardware repeatedly. To save design time and reduce the cost of the manufacturing hardware as well as to optimize the design process of a mechatronics system, this paper introduces an engineering model it is called a virtual prototyping technology which allows optimizing the designs on the computer before manufacturing the test-bed system. Based on the concept of the system working, the mechatronics system is designed on SOLIDWORKS and then exported to the ADAMS software (Automated Dynamic Analysis of Mechanical System). The flexible element is also modeling and analysis in ANSYS software then exported to ADAMS. The integrated simulation in ADAMS environment is executed to investigate the dynamic behaviors of the mechanical system and design will be adjusted. Virtual prototyping model will then be exported to MATLAB/Simulink to develop the control strategies. Co-simulation results in some contexts to evaluate the effectiveness of the proposed mechatronic system before implementing on test-bed

Abstract This paper focuses on virtual commissioning of a robotic manufacturing system, its theoretical background, and an analysis of its importance in the design of automated and robotic systems. Virtual commissioning allows the PLC control program to be tested and debugged on a created digital model of the machine, called a digital twin of the machine. Just this solution can simulate and optimize the automated system design itself without the need to have real hardware (PLC, automation elements, or the whole machine/equipment). Virtual commissioning offers an effective alternative to reduce the risks and effort of real commissioning of the machine. This makes it possible to reduce the time to market and increase flexibility, efficiency, and quality. Virtual commissioning in a single-control system is a simple solution; we can either use the Software-in-the-Loop method with emulated PLC control, simulated behavioural model, and co-simulation model or Hardware-in-the-Loop method with real controller. The problem appears when we have various types of controller, including an industrial robot controller. The paper deals with the theoretical background and partial outlines of solutions in the use of different types of the control system, if interconnections or emulators for different control systems are available. The recommended solution is to use a separate solution for the 3D simulation of the robotic system and an independent solution for the behavioural model, which will be tested in the future.

AbstractThe main objective of virtual commissioning is to help design and validate the control systems of entire production plants. Therefore, simulations on a logical and kinematic level are performed, typically in a Software- or Hardware-in-the-Loop configuration using the original control software and controller [1].However, the lack of level of detail means that this type of simulation is insufficient for an integrated system dynamics and control algorithms design. These engineering tasks are currently performed in separate tools, e.g. by finite element analysis, multibody simulations or by a combination, i.e. elastic multibody systems (EMBS) [2]. However, the designed components are only considered individually and not in the context of the control technology used. Therefore, primarily synthetic inputs are used and not the original control behavior. With a higher level of simulation detail, further questions about the system, such as the effect of control algorithms on the dynamic processes, can be virtually validated.Therefore, this paper explores hybrid component-based digital twins to combine the advantages of both VC and EMBS. Hybrid components allow the simulation of the interactions between process, machine and control system with a high level of detail where this is beneficial. Such integration is achieved using the Functional Mock-up Interface (FMI) to couple different simulation models in a co-simulation environment [3]. This is demonstrated in a simulation use case of an inverted pendulum. The level of detail of individual components in the virtual commissioning tool ISG-virtuos [4] is increased by the modular integration of elastic multibody simulations via FMI so that the swing-up controller can be designed in the simulation.

Social manufacturing is an internet- and social network-based platform where different manufacturers' capabilities can be seen and manufacturers with similar skills and hardware levels can come together to form communities. In the horizontal community, manufacturers who have similar socialised manufacturing resources and can perform the same processing activities are brought together. In the vertical community, there are manufacturers who can take part in different production activities of a product, from raw material to final product, and combine their socialised resources in this direction. Social manufacturing allows the bargaining power of the main producer to decrease thanks to the communities it establishes. The social manufacturing platform is a virtual showcase for small-scale entrepreneurs to present their talents, an effective cost management mechanism for customers, and an interaction, coordination, and sharing tool that will maximise production efficiency for countries.

Part of manufacturers’ responsibility when bringing out new products is to consider their environmental footprint. The legal supply chain combines hardware/software delivery, granting on-duty conformance to use preservation, and end-of-life take-back, with compulsory recovery targets. These entrepreneurial competencies appear externally, in respect to old manufacturing practices, which were internal. Networking options provide fundamental technological aids. This chapter analyses some technologically-driven solutions which stand out for the exploitation of net concerns at these three integration levels: business project co-operation, through spot-wise agreements; the factually united organisation or virtual corporation; joint and several liability, or extended corporation. The checks are centered on the bottom up series of appraisals, to evidence the return on investment from below so that the partnership permanently spurs motivation and fosters competition through properly established facilities/functions integration into unified competitive entrepreneurial organisations.

Abstract Additive manufacturing processes, especially those based on fused filament fabrication (FFF) mechanism, have relatively low productivity and suffer from production scalability issue. One solution is to adopt a collaborative additive manufacturing system that is equipped with multiple extruders working simultaneously to improve productivity. The collaborative additive manufacturing encounters a grand challenge in the scheduling of printing path scanning by different extruders. If not properly scheduled, the extruders may collide into each other or the structures built by earlier scheduled scanning tasks. However, there existed limited research addressing this problem, in particular, lacking the determination of the scanning direction and the scheduling for sub-path scanning. This paper deals with the challenges by developing an improved method to optimally break the existing printing paths into sub-paths and assign these generated sub-paths to different extruders to obtain the lowest possible makespan. A mathematical model is formulated to characterize the problem, and a hybrid algorithm based on an evolutionary algorithm and a heuristic approach is proposed to determine the optimal solutions. The case study has demonstrated the application of the algorithms and compared the results with the existing research. It has been found that the printing time can be reduced by as much as 41.3% based on the available hardware settings.

The design of modern gas turbine combustors continues to be driven by the demand for lower emissions of NOx and CO. Achieving reduced emissions on dry low emissions combustors necessitates the monitoring of associated, potentially destructive combustion noise. Power Systems Manufacturing (PSM) has developed a Dynamic Data Acquisition System for use in the noise performance optimization and health monitoring of low emissions combustors. Various noise probes and set-ups have been evaluated on test benches, combustion test rigs, and engines operating over their complete load range. The set-up and calibration of the combustion dynamic monitoring system is described here. An application of the dynamic data acquisition system is presented for the PSM combustor retrofit of the 85MW General Electric Frame MS7001EA machine, achieving 6ppm NOx, and 2ppm CO at base load and maintaining single digit emissions down to 50% load. The excellent condition of the combustion hardware following 8,000 hours of base load operation was indicative of operation in a low combustion noise environment. Combustion system noise monitoring ensures the lowest possible emissions, without compromising combustion hardware durability through excessive dynamic loading.

Abstract Activated Combustion HVAF (AC-HVAF) spraying provides efficient deposition of metallic and carbide coatings using solid particle spray technology. Oxidation and thermal deterioration of sprayed materials is significantly reduced, resulting in improved quality of coatings. Resistance of different WC-Co and WC-Co-Cr AC-HVAF coatings to abrasive wear was investigated using ASTM G-65 test. It was found that the AC-HVAF hardware setup, type of fuel gas and spray parameters affected deposition efficiency but not wear resistance of coatings. Herewith, the method of powder manufacturing revealed significant influence on coating wear resistance. The AC-HVAF sprayed coatings were compared to HVOF-sprayed counterparts, as well as to hard surfacing and chrome plating. The AC-HVAF sprayed coatings were efficient in competing with modern surfacing technologies in many industrial applications.

Component deterioration is observed in fleet gas turbine units during overhaul and maintenance activities of utilities providing electric power, co-generation or mechanical drive operations. Affected components include those provided by Original Equipment Manufacturers (OEM) and newly-manufactured and repaired hardware from OEM or aftermarket suppliers. This study details: i) the gas turbine flow path component deterioration and distress typically observed from operation, ii) some of the typical reasons (expected and abnormal) for the component damages, iii) the resulting effects and detriment to the utilities, and iv) a means for reducing the potential for component damages and operational risk to the utilities. Abnormal gas path component deterioration is one of the leading causes for forced opening of IGT units. Unscheduled opening of production gas turbine units during normal and critical operating time periods can result in significant costs to the utilities and insurance providers due to unplanned overhaul and maintenance costs, replacement components costs, and lost production revenue during the outage. Often the majority of the premature component deterioration within a set can be attributed to the quality of manufacturing or repair processing and inadequate inspections of the components. Escapes in quality assurance can occur resulting in components being supplied to utilities that do not meet design intent, such as debris contamination, coatings issues, and mis-machined features. Additionally, component suppliers are often pressured to meet production deadlines and provide delivery of the components to the utilities to avoid contractual penalties. This scenario can result in the potential for reduced focus on the quality of the components and quality-control escapes of design-deviated components delivered to the utilities for unit operation. Any uncontrolled deviations, damage, and discrepancies that result from hardware manufacturing and repair processes can have a significant impact on the long term durability of turbomachinery components. These component “damages” and manufacturing defects can be reduced or eliminated through proper functional quality inspections and component assessment, prior to unit installation. Additional issues concerning, improper tooling and methods employed during component removal and re-installation during maintenance activity can also result in damage to components and premature deterioration. This study focuses on how utilities can perform or audit the functional checks on components prior to unit installation in an effort to reduce component degradation, operational risk and potential of forced outage of units resulting in additional maintenance costs and lost revenue.

Embedded cooling techniques, utilizing microfluidic channels directly within a die substrate or in a miniature heat sink attached to the base of the die, have been known for decades [1] [2] [3]. Despite their demonstrated thermal benefits, such techniques and devices have not been successfully transitioned from the laboratory to either the commercial or military arena. Some of the hurdles preventing implementation to date have been the inability to miniaturize the supporting hardware, the high unit cost of fabricating individual microfluidic coolers, and the unknown reliability of the new technologies introduced. Recent advances in micro manufacturing and co-design/simulation capabilities have enabled significant progress to be made, aided by a significant new focus on embedded cooling technologies was recently initiated by DARPA [4]. This paper will present a recently fabricated embedded cooling system consisting of a state of the art, micro-miniature, 3D microfluidic manifold suitable for near term integration into existing systems. Computational fluid dynamics (CFD) and conjugate heat transfer (CHT) simulations demonstrate the ground breaking thermal performance achieved by the device, and coupled-field flow, thermal, structural and erosion simulations are also presented to address some of the reliability concerns. Finally, measured thermal performance is presented, validating the predicted thermal performance.

<div class="section abstract"><div class="htmlview paragraph">In the last decade, the accelerated advancements in manufacturing techniques and material science enabled the automotive industry to manufacture commercial vehicles at more affordable rates. This, however, brought about roadways having to accommodate an ever-increasing number of vehicles every day. However, some roadways, during specific hours of the day, had already been on the brink of reaching their capacity to withstand the number of vehicles travelling on them. Hence, overcrowded roadways create slow traffic, and sometimes, bottlenecks. In this paper, a Dynamic Speed Harmonization (DSH) algorithm that regulates the speed of a vehicle to prevent it from being affected by bottlenecks has been presented. First, co-simulations were run between MATLAB Simulink and CarSim to test different deceleration profiles. Then, Hardware-in-the-Loop (HIL) simulations were run with a Road Side Unit (RSU), which emulated a roadside detector that spotted bottlenecks and sent information to the Connected Vehicle about the position of the queue and the average speed of the vehicles at the queue. The DSH algorithm was also tested on a track to compare the performance of the different deceleration profiles in terms of ride comfort.</div></div>

The increasing complexity of electronics in systems used in safety critical applications, such as for example self-driving vehicles requires new methods to assure the hardware reliability of the electronic assemblies. Prognostics and Health Management (PHM) that uses a combination of data-driven and Physics-of-Failure models is a promising approach to avoid unexpected failures in the field. However, to enable PHM based partly on Physics-of-Failure models, sensor data that measures the relevant environment loads to which the electronics is subjected during its mission life are required. In this work, the feasibility to manufacture and use integrated sensors in the inner layers of a printed circuit board (PCB) as mission load indicators measuring impacts and vibrations has been investigated. A four-layered PCB was designed in which piezoelectric sensors based on polyvinylidenefluoride-co-trifluoroethylene (PVDF-TrFE) were printed on one of the laminate layers before the lamination process. Manufacturing of the PCB was followed by the assembly of components consisting of BGAs and QFN packages in a standard production reflow soldering process. Tests to ensure that the functionality of the sensor material was unaffected by the soldering process were performed. Results showed a yield of approximately 30% of the sensors after the reflow soldering process. The yield was also dependent on sensor placement and possibly shape. Optimization of the sensor design and placement is expected to bring the yield to 50 % or better. The sensors responded as expected to impact tests. Delamination areas were present in the test PCBs, which requires further investigation. The delamination does not seem to be due to the presence of embedded sensors alone but rather the result of a combination of several factors. The conclusion of this work is that it is feasible to embed piezoelectric sensors in the layers of a PCB.

The factory as a place of value-adding activities is forced to adapt continuously to turbulent conditions. New requirements regarding flexibility, speed, mobility and cost efficiency are some of factory planning. Hence the role of factory planning has developed from a one-time activity to a continuous management task. To achieve optimal results with regard to the new requirements it is necessary to analyze the existing processes and the functionality of the technical equipment at the workplace in detail. Therefore the existing methods of factory planning have to be improved. This paper focuses on the improvement of factory layout planning methods. One of the main areas of research of the Institute for Production Management and Enterprise Research (IFU) is the participatory layout planning. The goal of the research activities is to develop a method to integrate the employees from the shop-floor level into the planning process since they have special knowledge of the processes and technical equipment, which is necessary to achieve optimized planning results. To support the implementation of the participatory factory planning the IFU — in co-operation with the foresee GmbH — started the development of a participatory planning table called T3Pad (Tangible table top to enhance participation and development). The T3Pad is a conventional conference table with an integrated multi-touch display. The use of a gesture based software for layout planning offers the factory planning team the opportunity to design a layout by using the existing knowledge of the “classic” planning departments as well as the special manufacturing experience of the shop-floor employees. In order to realize the participation of the whole planning team the software has to comply with two major requirements: on the one hand the requirement in terms of the database and rules of factory planning; on the other hand the requirement of the usability of the software interfaces. Until now the users of factory planning methods have to adapt themselves to the function mode of computers instead of interacting and communicating in an intuitive way. This leads to limited interaction between user and hardware. The main goal of the T3Pad is an optimal support of the user by the software interface. To reach this goal the IFU started a field study to analyze the adoption of gesture based software interaction.
