摘要

以某DCT变速箱3挡预挂2挡为例，通过对敲击机理及影响因素的分析，获得精确的敲击灵敏度仿真和实验对比验证结果；制定了敲击灵敏度量化评价目标，并匹配不同飞轮进行实车验证，为变速箱敲击问题规避、曲轴系统及飞轮开发提供了依据。该研究对指导变速箱齿轮传动系统低噪声设计及发动机平台匹配具有理论意义和实用价值。

Abstract

Taking a DCT transmission preliminary gear 3 to 2 as an example，through the analysis of rattle theory and influence factors，the precise comparison verification result between simulation and test of rattle sensitivity are obtained. The quantitative evaluation target of rattle sensitivity is formulated，and different flywheels are matched for real vehicle verification. This research has theoretical significance and practical value for guiding low-noise design and matching engine platform of transmission.
