摘要
介绍了ODS方法的基本原理,该方法可以用来识别结构运行状态下的动态特性。应用该方法对某汽车变速器运转状态下的动态特性进行了分析,并根据振动与噪声的关系确定了变速器各噪声辐射面的主要噪声辐射区域,为变速器降噪提供结构改进的可靠依据。
Fundamental principle of ODS method is presented, which may be used to distinguish dynamic characteristics of a structure under operating state. The dynamic characteristics of a automobile gearbox under operating state has been distinguished with this method. Then the main noise radiating area of each noise radiating surface of the gearbox are ascertained according to the relationship of vibration and noise to provide a reliable basis for modification of the structure.
