履带式车辆路面反应谱测试的可行性研究

Feasibility Research on Road Response Spectrum Testing of Tracked Vehicle

通过测量车辆的振动加速度响应信号获取路面谱的方法具有很好的实用性。通过履带式车辆动态行驶过程中获得的振动响应信号,经过小波降噪预处理和系统辨识后可以得到履带式车辆悬挂系统的固有参数,说明实验方法具有较高的可行性,可以合理的反映出车辆的真实性能。实验中获得的采样数据具有一定的实用价值。

The method of getting road response spectrum by measuring vehicle vibration acceleration response signals is practicable. From the vibration - response signals got in course of the tracked vehicle＇s movement, the suspension parameters of the tracked vehicle can be got by de - noising preprocessing with wavelet analysis and system identification subsequently. And the feasibility of the testing method can be showed. The parameters can reflect the tracked vehicle＇s performance reasonably. The sampling data got from the testing have highly applied value.
