摘要

敲击噪声是变速器开发过程中面临的重要课题,而敲击噪声的测试方法研究在行业中还处于起步阶段。实践过程中,通过在变速器输入轴施加回转加速度,在变速器外侧测量噪声分贝值的变化,可以获得变速器敲击噪声随扭转加速度变化而变化的数据曲线。通过分析数据曲线,可以得知敲击噪声发生的起点以及敲击噪声对回转加速度的敏感度。
        The rattle is an important subject in the development of transmission,and the research on the testing method of rattle is still in the initial stage. In the practice process,by applying rotary acceleration in the input shaft of the transmission,measuring transmission external noise,the data curve of the transmission rattle changing with the rotary acceleration could be obtained. By analyzing the data curve,the starting point of the rattle and the sensitivity of the rattle to the rotary acceleration could be known.
