目前,当汽车在不平路面行驶时,关于汽车振动的一般概念是随机过程。由此来建立计算、试验和评价悬挂性能的方法。用随机函数的理论方法对悬挂进行的分析计算和在计算基础上对悬挂参数的选择会遇到一些实际困难。这是因为振动系统甚至仅研究纵向平面内的振动,也不是具有一个而至少具有二个输入——前轮和后轮(图1)。 Currently, the general concept of vehicle vibration when a car is driving on an uneven road is a stochastic process. To create a way to calculate, test, and evaluate suspension performance. There are some practical difficulties in the analysis and calculation of the suspension with the theoretical method of random function and the selection of the suspension parameters based on the calculation. This is because the vibration system does not even study vibrations in the longitudinal plane, nor does it have at least two inputs - the front and rear wheels (Figure 1).
