| Abstract: | By analyzing the dynamic characteristics of the drivetrain of SZG4031 towing tractor under heavy load, the simulation model of the self-excited vibration is developed. Using the phase plane method, the phase trajectory of the torsional vibration is drawn and verified to be a stable limit cycle which signifies self-excited vibration. The causes of self-excited vibration are explained with the principle of energy conservation. The factors which influence the amplitude of the self-excited vibration are analyzed parametrically. |
