摘要/Abstract

摘要： 针对车辆爬行工况下发生的严重变速器齿轮敲击问题，设计开发新型三级刚度扭转减振器，并通过专用台架试验和实车试验验证了三级刚度扭转减振器性能。首先，基于传统从动盘式扭转减振器结构特点，设计新型三级刚度扭转减振器机械结构并阐明其工作原理；其次，利用专用台架试验，测试得到从动盘式扭转减振器和新型三级刚度扭转减振器扭矩传递特性，验证三级刚度扭转减振器机械结构设计和性能参数设计的有效性；最后，设计实车道路试验，包括试验测试流程和传感器布置方案，综合试验信号时域、频域和时频域结果，对比分析传统从动盘式扭转减振器和新型三级刚度扭转减振器减振性能。结果表明，该新型三级刚度扭转减振器可有效解决原车在爬行工况下传动系统剧烈的扭转波动和变速器齿轮敲击问题。

Abstract: In order to solve severe transmission gear rattle problem on the vehicle creeping condition, a new three-stage stiffness clutch damper is designed and developed. The performance of the new three-stage stiffness clutch damper is validated by specific bench test and vehicle experiment. Firstly, characteristics of a conventional driven-disc torsional damper are introduced. Then a new three-stage stiffness clutch damper is proposed innovatively and its working principle is described. Secondly, by the specific bench test, torque transmission property of a conditional driven-disc clutch damper and a new three-stage stiffness clutch damper are obtained. Mechanical structure and performance parameters design of the new three-stage stiffness clutch damper are validated. Finally, experimental test process and sensor layout are designed in the vehicle road experiment. The damping performance of a conventional driven-disc torsional damper and the three-stage stiffness clutch damper are compared through these results in time domain, frequency domain and time-frequency domain. It's concluded that the new three-stage stiffness clutch damper could be adopted to inhibit severe driveline torsional vibration and transmission gear rattle problem on the vehicle creeping condition.

Key words: bench test, creeping condition, gear rattle, three-stage stiffness clutch damper, vehicle experiment
