| 摘 要： | 利用无线遥测的方法测量了车辆行驶条件下车轮的振动响应。对车轮振动响应进行了平稳性、周期性和正态性俭验,给出了车轮振动加速度均方根值随车速的变化关系。文中还讨论了车轮振动加速度功率谱密度峰值的性质,由于履带节的作用使车轮产生与车速有关的窄带随机振动。

The Measurement and Analysis of Vibration Response of Wheel |
| |
| Abstract: | The method of measurement of wheel vibration response in the case of tracked vehicle moving using radio telemeter is introduced in this paper.The test result shows that the vibration response of wheel is a stationary process which has Gaussian distribution. The relationship between the root of mean square for acceleration vibration response of wheel and the moving speed of vehicle is given. There is a sharp peak in the power spectral density of da- ta. It is a narrow band random vibration which depends on the moving speed of tracked vehicle. |
