Abstract:
This study was focused on the theoretical modeling and numerical investigation about the dynamic and static stiffness of coupled double-rotor spindle system of high speed grinder. The moment balance and the transition matrix, the state vector, field matrix of spindle system of high speed grinder were analyzed and deduced. The theoretical models about dynamic and static stiffness were established using the transfer matrix method. The numerical results showed that increased rigidity of front bearing significantly increased static and dynamic rigidity of spindle end and the rigidity of front bear

Abstract:
Processing precision of numerical control machine tool is decided by static rigidity and dynamic rigidity of spindle to a great extent. 3- D model of numerical control machine tool was established by using parametric modeling and virtual assembly function of Solidworks. Simultaneously, simulation and Experiment study of the spindle static rigidity was carried out, and practicability of the simulation analysis method was proved. The result indicates that the biggest deformation appears in the front of spindle. The static rigidity of spindle can been enhanced greatly by enhancing three carriage-

Abstract:
Static rigidity of workpeice spindle component is a very important index of the rigidity of derict-drive gear hobbing spindle unit. In this study, the static rigidity of workpiece spindle system were analyzed through a finite element method (EFM) by building geometric models and studying the deformation when radial cutting force was imposed. Experiments on workpiece were carried out with and without the assistance of tailstock center separately to measure the changes of the static rigidity of spindle. The results prove a less change of the static rigidity of spindle when with the assistance of

Abstract:
For a tensegrity framework with bars, cables (unilateral tension members) and struts (unilateral compression members), this paper presents a sequence of four mathematical concepts for detecting its rigidity. In order from the strongest to the weakest, these concepts are called infinitesimal (or static) rigidity, prestress stability, second-order rigidity and rigidity. Emphasis is placed on pre-stress stability, which lies between infinitesimal rigidity and second-order rigidity.

This article aims to investigate the fluctuation of the static rigidity for preloaded ball screws. Based on the correlation between preload and friction torque, a new model to calculate the contact rigidity by friction torque is proposed. Meanwhile, a novel test bench is constructed to measure the static stiffness at different positions. The experimental results agree well with the theoretical values, which proves the validity of the model. Furthermore, it is found that the screw shaft rigidity has the greatest influence on the system stiffness fluctuation, compared to the bearing rigidity, an

Abstract If prices do not adjust, it is natural to associate this fact with adjustments being costly. It is rather obvious that costly price adjustments-or so-called menu costs-will make prices less flexible than they would be in the absence of such costs. It is also intuitive that if these costs are fairly ‘small ‘ we should expect firms to avoid price adjustment if they are exposed to only ‘small ‘ shocks, while they will find it worth while to adjust to ‘larger ‘ shocks. Is this all, or do the costs of adjusting prices have other less obvious implications? This chapter addresses this questi

Abstract:
Structure-from-motion studies typically employ motion sequences in which any single frame is devoid of any 3D structure information. Real world sequences, however, present the observer with both dynamic and static form cues. To investigate how these concurrently active sources of 3D information interact, we designed stimuli that, upon moving, provide inconsistent structure cues, i.e., the form cues suggest a 3D organization different from that indicated by motion cues. We showed (Sinha, 1992) that in such stimuli form cues can overwhelm the motion cues and that the rigidity assumption is extre

Abstract:
Instrumented static load testing is an effective means for assessing load-transfer characteristics of augered cast‑in‑place piles under static axial load. Strain gauges are typically instrumented on the steel reinforcement at specific locations along the pile’s embedded length for determining geotechnical resisting forces in side-shear and end-bearing. Conversion of strain to internal force at each gauge level can be complicated, requiring critical assessment of the pile properties and potential strain-dependent behavior. Current codes and standards provide recommendations for approximating th

Abstract:
The hollow extrusion-type material made from aluminum alloys has recently attracted attention, and it has been used for the car bodies of high-speed railway vehicles. Hollow extrusions are laminating board structures that consist of a two-sheet board and slanting material known as a double skin structure. The double skin structure is advantageous in attaining a lightweight car body structure and in increasing rigidity in case it bends outside and the pressure load at the time of the run in tunnel acts, since rigidity is high. In this study, static tests were carried out for component models an

Abstract With the development of machine tools trending toward high precision, intelligence, multi-axis, and high speed, the improvement of the processing performance and rigidity of the machine is considerably important. The objective of this study is to design of a high-speed five-axis moving-column machine tool and perform structural analysis and optimization. We study the static and dynamic characteristics of the five-axis machine tool, design and improve the mechanical structure, and optimize the structural configuration of the machine. The entire machine structure is further analyzed and

Abstract:
This paper analyses the dynamics of policymaking among the various political institutions in Uruguay. The authors find that first, there are relatively stable policies, such as those allowing for the commercial and financial openness of the country. Then there are inflexible and low-quality policies, such as those related to social policies, some areas of state reform (civil servants' wages and hiring mechanisms), the bankruptcy regime, etc. Finally, there are volatile outcomes resulting from economic shocks, such as those related to discretionary public spending.

This paper study the issue of institutional enforcement of regulations by focusing on labor-market policies and their potential link to economic performance. It test the different impacts of enforceable and non-enforceable labor regulations by proxying non-enforceable labor rigidity measures using data on conventions from the International Labor Organization (ILO). It has been argued that non-enforceable conventions -that is, those that exist on paper and are simply de jure regulations -appear to be more distortionary and tend to be the least enforced in practice (Squire and Suthiwart-Narueput

As the State of California continues to grow, demand for enhanced infrastructure such as roadways and highways escalates. In view of the current average highway lifespan of 15–20 years, the improvement of asphalt binders leads to material sustainability by decreasing required maintenance and increasing the lifespan of roadways. In the present investigation, enhancement of asphalt binder properties was achieved by different methods of mixing varying compositions of graphene nanoparticles with an SBS polymer and asphalt binder.

Systematic experimental studies were performed for the purpose of obtaining the material properties of cold-formed sorbite stainless steel and the mechanical parameters of plug-pin joint. As a new type of material, the scaffold made of sorbite stainless steel has the advantages of convenient construction, high strength and stainless steel. The static tensile tests for S500 sorbite stainless steel investigating the material characteristics of plug-pin joint were carried out. The bending moment, the compressive force, the tensile force and the shear force were applied to the joint respectively.
