六、整车系统的输入谱到目前为止仅仅建立了系统的模型,欲求出整车系统的响应,必须正确地描述系统的输入。1.确定输入方式采用什么样的输入方式解方程(29),这主要取决于研究的目的。一般来说,求周期激励的响应,如发动机的周期激励响应,最好的输入激励讯号是离散富代谱;求汽车过凸起的瞬态响应,可直接用凸起的形状,在时域里用数值积分方法求得;求路面随机激励的响应,最
Sixth, the input spectrum of the vehicle system So far only established a model of the system, want to get the response of the vehicle system, the system must correctly describe the input. 1. Determine what kind of input method used to solve the input equation (29), depending on the purpose of the study. In general, the response of the periodic excitation, such as the periodic excitation response of the engine, the best input excitation signal is the discrete generation rich spectrum; seek the transient response of the vehicle over the convex, can be directly convex shape, in the time domain In numerical integration method to find; find the response of road surface random excitation, most
