摘要
为了解决某四缸发动机平衡轴啸叫问题,采用CAE仿真分析和NVH试验研究相结合的方法,分析了平衡轴啸叫噪声与齿轮齿形、齿向参数的关系。研究结果表明:齿向起鼓Cβ、齿向螺旋fHβ、齿形起鼓C_(α)、齿形压力角f_(Hα)是影响平衡轴啸叫的主要齿轮参数,通过CAE仿真分析结合NVH试验确定最佳的齿轮参数修形方案,能够有效地解决因齿轮啮合不当产生的啸叫噪声。
For solving the problem of squealing noise of the balance shaft of a four-cylinder engine,we use CAE simulation analysis and NVH experimental research to analyze the relations of abnormal noise and gear parameters.The results show that axial crowning Cβ,axial spiral angle fHβ,radial crowning Cαand radial pressure angle fHαare the main parameters that affect the abnormal noise.Finally,we determined the optimal gear parameters by CAE simulation analysis and NVH test to solve the problem.
