摘要/Abstract

摘要： 本文中针对双质量飞轮的性能展开台架与整车试验研究。首先分析了扭转角度对双质量飞轮静态扭转刚度的影响;其次对双质量飞轮样件进行台架试验,通过台架试验验证理论分析的正确性以及其刚度值满足扭转刚度设计要求;最后对双质量飞轮开展实车道路试验,分别获得怠速、匀速、加速、减速多工况下双质量飞轮对传动系扭振的减振性能。试验结果表明,双质量飞轮在各个工况下对传动系扭振都有明显的衰减效果;稳态工况(怠速、匀速)下双质量飞轮扭振衰减幅度约50%;非稳态工况(加、减速工况)下扭振衰减幅度约80%。

Abstract: This paper studies the performance of dual mass flywheel by bench and vehicle tests. Firstly, the influence of torsion angle on the static torsional stiffness of dual mass flywheel is analyzed. Secondly, the bench test of the dual mass flywheel sample is carried out to verify the validity of the theory and prove its stiffness value meeting the design requirements of torsional stiffness. Finally, the road test of the dual mass flywheel is carried out to obtain the torsional vibration damping performance of the dual mass flywheel in the transmission system under idle, constant speed, acceleration and deceleration conditions. The test results show that the dual mass flywheel has obvious damping effect on torsional vibration of the transmission system under various working conditions. Under steady-state conditions (idle, constant speed), the torsional vibration attenuation of the dual mass flywheel is about 50%; under unsteady conditions (acceleration and deceleration), the torsional vibration attenuation of the dual mass flywheel is about 80%.
