Analysis of Vibration Characteristics of Tracked Vehicle Based on Experimental Tests

In order to reveal the mapping relationship between the degradation characteristics and vibration characteristics of tracked vehicle components, a vibration test system is built to test the vibration characteristics of typical positions of tracked vehicle under common driving conditions. Then, the correlation between the vibration value of the test point and the vehicle speed is established by using a logarithmic linear regression model, and the correlation of the vibration between different test points is analyzed. Finally, through mining the vibration characteristics of typical positions of the transmission device, the signal feature that can effectively characterize the degradation trend of the components can be extracted, which is helpful to realize the assessment of vehicle health and failure warning. This research has certain reference value for optimizing the layout of test points and improving the functions of the on-board system of prognostics health management.
