| Abstract: | Self excited vibration in vehicle powertrain occurs in some cases and damages vehicle performance such as tractive performance, etc.. In order to study the regularity and cause of the self excited vibration, experiments of a BJ2020N jeep on various roads, with various tire pressures and several drawbar forces are carried out. Experimental result indicates that there really exists self excited vibration in vehicle powertrain when vehicle runs at high slip. Features of the self excited vibration and the influence of tire pressure and road condition on the self excited vibration are also studied. As a conclusion, the amplitude of the self excited vibration grows as tire pressure increases. |
