摘　　要：文章针对某电驱动车型在匀速及减速滑行工况下30 km/h的齿轮啸叫问题,借助LMS Test.Lab测试分析系统进行了啸叫问题详细诊断和分析。通过对齿轮参数进行检测分析,确定了该噪声产生的根本原因。最终通过优化砂轮参数,解决了啸叫问题。该研究思路为后续类似问题的解决提供了重要的参考价值。In this paper,for the gear whine noise problem of the electric car at 30 km/h under the uniform speed and the coast condition,the LMS Test.Lab test and analysis system is used to problem diagnosis and analysis.By testing the gear parameters,the root cause of the noise was identified.Finally,the noise problem was solved by optimizing the grinding wheel parameters.The research idea provides an important reference value for the subsequent solution of similar problems.
