Abstract: | A single wheelset drive model and 2-DOFs torsional vibration model were established to investigate the self-excited torsional
vibration of a locomotive driving system. The simulation results indicate that the self-excited torsional vibration occurs
when the steady slip velocity is located at the descending slope of the adhesion coefficient curve. The principle of energy
conservation was used to analyze the mechanism of the self-excited vibration. The factors affecting on the amplitude of the
self-excited vibration are studied. |
