Dynamic optimization of tracked vehicle power train based on torsional vibration analysis

Dynamic optimization of tracked vehicle power train based on torsional vibration analysis

Aiming at the vehicle power train, system dynamic optimization is profoundly studied based on the system torsional vibration characteristics analysis. First, based on the concentrated mass method, the general torsional vibration model of vehicle power train is established and solved after parameters...
