在研究机器的降噪问题时,首先必须鉴别机器的噪声源,分清其主次,以针对主要噪声源采取措施,才能取得降低整机噪声的效果.常规的噪声源鉴别方法有多种.但各种方法均有其一定的局限性.在鉴别一台具有多个声源的复杂机器时,常不得不同时采用几种方法综合分析作出判断,因而很费时间.声强测试技术的发展提供了一种能准确而方便地鉴别噪声源的方法.本文介绍了声强测试技术鉴别噪声源的方法及在分析摩托车噪声源中的应用.摩
When studying the noise reduction of a machine, firstly, it is necessary to identify the noise source of the machine, distinguish its primary and secondary, and take measures against the main noise source to achieve the effect of reducing noise of the whole machine. Various methods have their own limitations.In the identification of a complex machine with multiple sound sources, often have to use several methods to make a comprehensive analysis of judgment, which is time-consuming.Development of sound intensity testing technology provides A method that can identify the noise source accurately and conveniently.This paper introduces the method of noise intensity testing to identify the noise source and its application in the analysis of the noise sources of motorcycles.Mo
