| Abstract: | 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. |
