摘要：

基于AMESim仿真平台，建立某双离合变速器车型传动系统全阶撞击声模型，并通过试验验证了模型的精度。分析在4挡急踩油门工况下，传动系统各间隙的撞击声响应，发现非承载零部件也是冲击的主要贡献部件。通过分析系统部件的运动关系，确定潜在影响参数，得出各参数对系统撞击声的影响。最终结果表明，发动机转矩是系统撞击声最主要的影响参数，控制发动机转矩上升斜率是降低撞击声的重要手段。

关键词: 传动系统, 间隙, 冲击声, 转矩斜率

Abstract:

A full?order clunk model for the driveline of a vehicle with dual clutch transmission is established based on AMESim simulation platform， with its accuracy verified by test. The clunk responses of all backlashes in driveline are analysed under the 4th gear tip?in condition， and it is found that some unloaded components are also the major contributions to clunk besides the loaded ones. By analysing the motion relationship between system components， the potential influencing parameters are determined， and the effects of each parameter on system clunk are revealed. Finally， the results show that engine torque is the most dominant influencing parameter on system clunk， and the control on the rising slope of engine torque is the important means of reducing clunk.

Key words: driveline system, backlash, clunk, torque slope
