This paper describes the effort and accomplishments for developing flexible fabrics with high thermal conductivity (FFHTC) for spacesuits to improve thermal performance, lower weight and reduce complexity. Commercial and additional space exploration applications that require substantial performance enhancements in removal and transport of heat away from equipment as well as from the human body can benefit from this technology. Improvements in thermal conductivity were achieved through the use of modified polymers containing thermally conductive additives. The objective of the FFHTC effort is to significantly improve the thermal conductivity of the liquid cooled ventilation garment by improving the thermal conductivity of the subcomponents (i.e., fabric and plastic tubes).

Using the nonlinear finite element analysis, three nonlinear characteristics of the rubber gasbag of the air spring on the bus are thoroughly analyzed, including the nonlinear characteristic of the rubber gasbag with multi layers of composite materials, the nonlinear large displacement geometry characteristic of the rubber gasbag on working, and the nonlinear contact characteristic of the rubber gasbag when contacts the pedestal and the top cover plate. A model is build and the nonlinear characteristic of the air spring on the bus is analyzed using the ABAQUS software. At last, the article discusses parameters that influence on the characteristic of the air spring for the bus.

In modern car, to reduce car deadweight, lightweight technology is widely used; and to improve comfortable and handling performance, many rubber bushings installed between car body and suspension. These parts have difference characteristics during car running at high speed comparing these at static state. Accounting the suspension performance has a decisive influence on a car, the flexible parts should be taken into account in the suspension/steering system simulation model. As a deviant phenomenon, the steering wheel shimmy affects the suspension's dynamic characteristics greatly. To analysis this abnormal running state, the front wheel bounce tracks were figured out by using different front suspension model. The flexible parts installed in suspension are idealized respectively as rigid poles, flexible beams or forces, hence, the rigid suspension analytical model and the rigid-elastic suspension model analytical were built respectively.

Based on the theory of multibody system dynamics, some characteristics of the Mcpherson independent suspension (Audi 100 front suspension) are analyzed. The planar and spatial models consisting of multiple closed-loop systems with rigid and deformable bodies are included in the study. In the planar analysis, Lagrange method is used to develop dynamic equations. In the spatial analysis, a special and practical method to transform system stiffness to the wheel center is used to simplify the calculation process and obtain the satisfactory results more easily. As an example, a result of turning behavior is given to show that the method introduced is effective to investigate some effect of the parameters of the suspension on car performance. Specialized test techniques are implemented to obtain the mechanical property of the components which is necessary in the analysis.

The use of the hydraulic mount and sub-frame (engine cradle) for passenger car is increasingly becoming common in the automobile industry because they can provide excellent frequency and amplitude response characteristics compared to the conventional elastic rubber type engine mount. The 14-degree-of-freedom dynamic model of engine and sub-frame mount system is developed in this paper. The method to solve second-order-differential equation which include variable stiffness and damping is given. A lot of calculation and measurement of vibration response are carried out. It is shown that hydraulic mount and sub-frame mount can effectively isolated the vibration transmitted from engine to body.
