某新型车辆在基于MATLAB环境中随机路面下平顺性探析

通过在典型正弦信号激励下仿真,研究两种阻尼系数下的车身振动。然后在不同车速及路面工况下采用多种阻尼进行仿真,找出减振器阻尼系数对整车垂直振动加速度及位移的影响,为减振器设计提供理论阻尼参数,也为车辆在行进过程中保持车内货物不受损坏提供理论基础。

Study on Smoothness of a New Type Vehicle on Random Road Based on Matlab

The thesis makes an investigation on the body vibration of the car by studying the emulation of typical sinusoidal signal under the two kinds of damping coefficient.It tries to get the result that the damping coefficient of vibration absorber has a great effect on the acceleration and displacement.It will afford the data of the damping parameter for the design of the vibration absorber in theory,and offer theory basis to keep objects from attaint in course of truck march.
