Повний текст джерелаThis research aimed to verify whether the methodology of Design Thinking (DT) and the Theory of Inventive Problem Solving (TRIZ) could be used together synergistically in the conceptual phase of a new product development project (NPD) in the automotive industry through the also know APQP (Advanced Product Quality Planning) process. The main purpose was to leverage the creativity by generating ideas that are more qualified and, at the same time, select the best product concepts to be taken to the next phases of the NPD. This research seeks to understand within the literature the strengths and limitations of each of the methodologies and, at the same time, a proposal is made on how to integrate them into the APQP methodology. The proposed process is then tested in a project of mass reduction of the door body seal of an automotive vehicle. As shall be demonstrated, the automotive NPD, by using the improvement proposal, will become more effective by leveraging the creativity while consolidates a conceptual stage within the APQP. Through this research, it is concluded that both methodologies are synergistic and, therefore, can bring improvements for the current APQP process by leveraging the quality and assertiveness of the generation of ideas, as well as supporting to select the best concept to be taken to the next phases.

This thesis cites the human body mechanical model as the basis of the design of active suspension system using the 1/4 vehicle model and 1/2 vehicle model. The study considers the root mean square value of vertical acceleration of the passenger head as indicators of comfort referred to the whole-body vibration limit of ISO 2631-1(1985) to specify the human-body exposure to vibration environment. The design of active suspension systems combines the genetic algorithm with fuzzy control theory. The genetic algorithm is used to adjust the control parameters of fuzzy controller. The fuzzy controller uses the vertical acceleration of passenger head, and its rate of change as feedback to reduce the mean square value of the vertical acceleration of passenger head. The numerical results show that although the active suspension system of vehicle is designed mainly to reduce the passenger head acceleration at a specified speed travelling on an irregular road, it also provides the same improvement level for the other parts of body and different travelling speeds. And the active suspension systems have obvious improvements on the comfort of passengers regardless of the irregular road or the step road.

This thesis presents a vibration isolation optimum design of automotive seating system based upon a half-car model. The vehicle body is simulated as an elastic beam equipped with an active suspension system which possesses a fuzzy controller using the vertical accelerations of front and rear seats, and their rates of change as feedbacks. The mean square values of the vertical accelerations of front and rear seats are chosen to be the fitness function, and the constrained conditions of suspension travels and tire deflections are added as a penalty function. In the study, the vehicle is simulated to travel on an irregular road surface. The proposed genetic algorithms are then applied to adjust both the membership functions and the fuzzy rules so as to reduce the vertical acceleration levels of front and rear seats. The simulating results indicate that compared to the passive suspension system, the improvements on the vertical acceleration of front seat is about 30%, on the vertical acceleration of rear seat is about 40%. This optimal system is also testified on the step road surface and found that the maximum accelerations of front and rear seats are still smaller than those obtained by the passive system. Also, the front and rear suspension travels, and tire deflections are all within the tolerant range to ensure that the suspension system works normally and the wheel provides enough road holding. It is concluded that the fuzzy controller designed by the proposed genetic algorithms can efficiently reduce the vertical accelerations of front and rear seats to improve the passenger ride comfort without influencing the ride safety.

In this thesis, the lightweight design analysis process for an electric vehicle body structure with five seats is proposed. The lightweight analysis process combines topology optimization analysis and finite element model analysis. The design weight of the body structure is set to be less than 200 kg.The bending stiffness and the torsional stiffness of the body structure are design to be greater than 4000 N/mm and 2000 N.m/deg, respectively. In this research, the Hyperwork topology optimization software is used for the lightweight analysis of the body structure. Three dimensional finite element models are proposed for modal analysis,stiffness,strength,collision, and fatigue life analyses of the body structure using the commercial finite element software ABAQUS. The results indicate that the weight of the proposed body structure is 180 kg according to the lightweight design analysis process. The first bending frequency of the body structure is 26.5 Hz. The bending stiffness and the torsional stiffness of the body structure are 4310 N/mm and 2198 N.m/deg, respectively. A collision simulation has been made at the speed of 40km/hr. The results show that the vehicle longitudinal shrinkage deformation of the body structure is 451 mm. The shrinkage deformation of footwell area is 95mm. The results obtained from the collision analyses also show that the proposed body structure can satisfy the required specifications of European Union ECE R94 and ECE R95. The simulation results show that the fatigue life of the body structure is reduced as the road roughness level increases. In this study, the fatigue lives of the proposed body structure are 6.76×1010,1.31×107,1.21×103and1.5×101 under the conditions of the road level A,B,C and D, respectively.

The main objective of this research is to perform the mechanism design of a body-tilt bogie from the viewpoint of kinematics. This research collects all kinds of body-tilt bogies for railway vehicles from academic journals and patent publications. The collected literatures are systematically studied and classified. All body-tilt bogies are classified according to the driving modes or the types of mechanisms. The driving modes include active- and passive-type, while the types of mechanisms include linkage-, roller-, bearing-guide-, anti-roll-bar-, lever-, and direct-input-type. Some of the body-tilt systems have been successfully commercialized; while some of them are developed to resolve problems found in the current body-tilt bogie systems, such as the positions of the vehicle mass center and the tilt center, as well as the static and dynamic enveloping surfaces and the tilt control of the bogie system. It can be seen that the improvement of the body-tilt bogie must restrain the position of the vehicle mass center, reduce the shift of weight between inner and outer wheels, and comply the static and dynamic enveloping surfaces provided by Tai-Railway. The new design is synthesized by using dyad- and triad-synthesis technique. A four-bar and an eight-bar tilting mechanism are synthesized to improve the performance and to comply Tai-Railway’s regulations. The resultant eight-bar linkage has better kinematic characteristics compared to the four-bar tilting system. Computer aided dynamic simulations and analysis are conducted, by using Pro/ENGINEER and Pro/MECHANISM to verify the kinematic properties of the new body-tilt bogies. This research has also performed detailed kinematic analysis and static-force analysis of the new designs.
