轴承结构引起的固有振动所产生的噪声数学模型的确定

A determination on the mathematical model of bearing noise by vibration of its structure

利用声学理论中的典型声源结构建立了由轴承结构引起的固有振动所产生的噪声数学模型 ,为研究滚动轴承的降噪减振提供了理论依据。同时根据现场的试验情况 ,对该数学模型进行了验证 。

A mathematical model of bearing noise by vibration of its structure is established by the classical sound model of sound theory Meanwhile, this model is verified by testing, and it is possible for the results
