标准范围

本文件规定了一种通过在试验台上的测量来预测接收结构上的活动部件产生的动态力的方法。它规定了适用于试验台和设置动态力测量条件的要求:例如,可以建立传递函数测量有效性的标准。目标是评估安装在接收结构上的有源部件产生的噪声和振动,包括优化隔振器的可能性。它可以应用于连接到建筑物的不同系统,例如压缩机或发电机,或连接到车身的系统,例如发动机动力传动系统或电动执行器。

This document specifies a method to predict the dynamic forces generated by an active component on a receiving structure from measurement on a test bench.It sets out the requirements applicable to test benches and setup measurement conditions of dynamic forces: a criterion of validity of transfer functions measurements can be established for example.The objective is to evaluate noise and vibrations generated by active components mounted on receiving structures, including the possibility to optimise vibration isolators.It can be applied to different systems connected to a building, such as a compressor or a power generator, or to systems connected to a vehicle body, such as an engine powertrain or an electrical actuator, for example.
