评价齿轮箱产生于结构噪音的一种改进方法

An Improved Method of Estimating the Structrureborne Noise of Gearboxes

在设计阶段,如果我们可找到一种计算激励力、产生于齿轮箱结构的噪音和噪音的传播特征的方法,那么,由齿轮传出的噪音就可以用计算来预测。作者提出的一种评价方法,用它来实际确定齿轮机体的声响特性是合理的。其理论结果已被实验研究所证实。

The noise radiated by gear units can be predicted by calculation during the design phase if a method can be found for calculating excitation forces and the structure- borne noise and sound radiation characteristics of the housing body. The author presents an estimation method which is appropriate for practical statements about the acoustic quality of the housing. The theoretical results are confirmed by experimental investigations.
