摘要
本文是一篇科研工作总结。主要论述ISO4412/1国际标准规定的在半消声室的环境下,对液压泵空气噪声声功率级的测定,并以对该标准进行验证的菇式,分析测定的特点和影响的因素。同时介绍该国际标准对液压泵噪声测定的一些规定。
This paper discusses determination of the sound power level of hydraulic
punp's airborne noice under the condition of semi anechoic rooms based on ISO 4412/1.The
testing features and the affecting factors are to be analized by certifing this stanndard.Some
stipulations of ISO on measuring hydraulic pumps noice are also introduced.
