摘要
为了评价垂直振动和俯仰振动对汽车平顺性影响,建立汽车四自由度振动模型。通过拉普拉斯变换推导数学模型。基于MATLAB软件,对推导的数学模型进行编程,分析了车身垂直振动、俯仰振动对前后轮的激励影响,前后轴振动对前后轮激励的频率响应。
In order to evaluate the vertical vibration and pitching vibration of vehicle, the establishment offour degrees of freedom vehicle vibration model. The mathematical model is derived by Laplasse transformation.Based on the MATLAB software, derivation of the mathematical model is programmed, analyses the incentiveeffect on the front and rear body from vertical vibration and pitching vibration and frequency responseon front and rear wheel drive formfront and rear axle vibration.
