摘要以单级人字齿轮减速器箱体为研究对象，采用FEM/BEM方法计算了箱体的辐射噪声，分析了箱体振型对辐射噪声的影响。通过计算各阶模态的模态参与因子以及模态声学贡献量，确定了对箱体输入侧、输出侧场点上的辐射噪声贡献最大的模态阶数。依据模态声学贡献量分析结果，提出了肋板和阻振质量的合理布局方式。分析结果表明，箱体各面板的弯曲振型对辐射噪声的影响最明显；当声学贡献最大的模态确定后，在对应振型中各面板弯曲振型最明显的位置添加肋板或阻振质量，可明显降低面板同侧场点上的辐射噪声。

Abstract：The radiated noise of gearbox with a double helical gear system is calculated using FEM/BEM and the influence of mode shapes on radiated noise is analyzed. The modal participation factors and modal acoustic contributions of each mode are calculated and the mode having maximum contribution to the radiated noise on the input and output field points is found. The reasonable arrangements of ribs and isolate masses are proposed according to the analysis of modal acoustic contributions. The results show that the flexural vibration of gearbox housing has most obvious effect on the radiated noise. When the mode having maximum acoustic contributions is found, the positions on each panel having obvious flexural vibrations can be obtained and the radiated noise on the field points at the same side with the panel can be reduced by adding ribs or isolation massed on these positions.

Key words： gearbox mode shape modal participation factors modal acoustic contributions noise
