摘要
利用改进的非高斯闭合法 ,通过计算讨论了汽车在路面谱激励下 ,减振器非线性阻尼对车身振动加速度均方根值、车轮与路面间相对动载荷及悬架穿越频率的影响规律。通过与试验结果对比 ,证明计算结果和所得结论正确。
In this paper, with the application of Non Gaussian closure, effects of the nonlinear damping of shock absorber on the root mean square of auto body vibration, dynamic load appling on the wheels from the road surface and the passing through frequency of suspension, under the road spectrum random excitation, are analyzed by calculation. Comparison between the calculation and the test shows the both results of calculation and the conclusions are correct.
