乘用车起动异响的分析及研究

Analysis and Study of the Vehicle's Starting Abnormal Noise

随着消费者对乘用车舒适性及NVH性能的要求不断提高,针对某车型起动异响的问题,对起动机起动噪声产生的原因及影响因素进行了分析。通过对起动机起动过程中的噪声进行测试和分析,研究了齿轮重合度的调整对起动机起动噪声的影响。通过优化齿形参数,提高重合度,有效地解决了该车型起动异响的问题。

As the consumers'increasing requirements for vehicle's comfortableness and NVH performance,according to the problem of starting abnormal noise of a certain type of vehicle,the causes and influencing factors of starter noise is analyzed,and the influence of the adjustment of the gear contact ratio on the starting noise of the starter is studied through the starter noise test and analysis.Through improving the contact ratio by changing the tooth shape parameters,the problem of abnormal noise of the starter is solved effectively.
