摘要
对基于有理函数的路面不平度白噪声激励模拟方法进行了分析,指出了该方法存在的不足。提出了一种基于幂函数的路面不平度白噪声激励模拟方法,并对其两轮路面不平度输入的白噪声激励模拟方法进行了推导。通过对不同等级路面的仿真,验证了所提出方法的可行性。
The method of white noise simulation on road roughness based on rational function is analyzed with its disadvantages pointed out. For this, a method of white noise simulation on road roughness based on power function is put forward with that method for two wheel vehicles derived. Through the simulations on different grade roads, the feasibility of proposed method is verified.
