用测振法检测机电产品噪声的研究

Determine the noise of the machinery with measure vibration and produce instrument

本文阐述了一种能在生产现场条件较差的情况下测定其机电产品噪声值的较为理想的方法,即用测量机电产品表面的振动量来确定空气噪声辐射,从而比较精确地测定其机电产品的噪声值。本文同时还介绍了通过对几种机电产品振动特性的研究,得出实际的辐射效率曲线,并研制成的相应的测量仪器。

This article expounds how to measure the noise decibel of the machinery and under poor manufacture conditions. The method mentioned in the article is to measure the vibration of the surface of the machinery and noise radiation in the air so that the noise decibel of the machinery can be precisely determined. This article puts forward actual radiation efficiency curve from the base research of vibration character on the machinery and produce measure instruments according to research .
