浮筏隔振装置隔振效果评定

Evaluation of Isolation Effect of Floating Raft System

本文基于信号能量的观点 ,分析了用振级落差评定浮筏隔振装置多扰动特性和多向隔振特性的原理 ,提出了能量叠加的评定方法 ,并用实测数据进行了验证。

The property of multiple exciting forces and mixed direction of the floating raft system are analyzed in this paper in terms of level difference,based on the viewpoint of signal energy.The evaluation method of signal energy superposition is presented,and the result is confirmed by test data.
