| 摘 要： | 综合考虑齿轮时变啮合刚度及齿轮误差的影响建立了齿轮系统动力学模型，计算得到了齿轮系统动载时域历程。建立了齿轮箱声固耦合系统模型，采用边界元法对其噪声辐射进行求解，得到了齿轮箱噪声谱及各板面对声场总声压的贡献度。依据板面贡献度计算结果，对齿轮箱结构进行适当改进，对结构的改进及结构阻尼对降噪效果做出了分析，就不同齿轮类型对齿轮箱噪声辐射的影响进行了讨论，为齿轮箱的设计提供了理论依据。

| Abstract: | The dynamic model of the gear transmission system is built in consideration of the time-varying mesh stiffness and the gear errors. Then the time history of the dynamic load of system is obtained. The gear box structural-acoustic coupling system is built and calculated by using BEM. The noise spectrum of the gear box and the panel contribution are obtained. The effect of the gear box structure improvement, structure damping and different gear style on the noise radiation is analyzed. The study provides useful theoretical guideline to the design of the gear box. |
