| Abstract: | In order to solve the vibration problem of a tracked vehicle on flat hard road, the vibration characteristics about the vehicle and its variant vehicles have been tested, and the formula about the vehicle speed and its hull＇ s vibration frequency has been derived based on an assumed excitation. The calculating results obtained from the formula were coincided with testing ones of acceleration PSD, verifying the correctness of the assumed excitation. Three solutions of vibration reduction on the sprocket design have been proposed. |
