Abstract
This article made research of several mechanical problems which related to the car movement, include the problem of the maximum acceleration when brake the car, the relationship between the speed and braking distance, the damping function of suspension system, the additional pressure made by the movement that rigid body circles round the axis. These problems are closely related to the comfortableness, security in car driving. In the car manufacturing and development process, the comfortableness and security has always been the goal. As direct and specific forms for these goals, it has continually developed with the support of new technology and presents a trend that multiple subjects across, multiple technologies integrate, multiple theories overlap. But in which, mechanical principle as a basis is can’t be replaced; analysis to mechanical model is indispensable. This article is from the requirements of tracing the source, by linking theory with practice, using learned knowledge, to establish ideal model to these problems. On this basis, making careful analysis and investigating the most fundamental mechanical principle that included in these problems.
Keywords: balance damping additional pressure sliding friction suspension system
