轿车翻覆与车轮正压力的关系研究

The Car Wheels' Normal Pressure and Turning Over

建立了轿车启动与刹车时的力学模型,应用刚体动力学中的动静法与动能定理、摩擦理论以及机械传动的有关知识,分析了轿车在启动与刹车过程中的加速度与车轮的正压力的关系,并给出了动力参数与尺寸参数之间的关系式。

When the car is staring or braking, its mechanical model is built in this paper. By applying some principles of dynamics t cluding methods of kineto statics, theorem of kinetic energy and friction theory, etc. and theory of machines, this paper analyses the ralation on the car wheels＇ normal pressure and the car＇s acceleration. The relation formula of dynamic paremeters and paremeters of mersure is given here.
