一、前言近年来,有关通过减振达到降低噪声的阻尼板的研究应用获得了较快的发展。作为这类板材性能指标的损耗因子η,已有不少的测定方法。目前主要的方法是共振法。应用该法的自动测量系统在文献[1]中作了介绍。本文专门叙述对共振特性采样时包含的诸误差因素的模拟研究结果。
I. Introduction In recent years, the research and application of damping plates that achieve noise reduction through vibration reduction has achieved rapid development. As a kind of sheet material performance index loss factor η, there are many measurement methods. The main method is the resonance method. The automatic measurement system using this method was introduced in [1]. This article describes in detail the simulation results of the error factors involved in sampling the resonance characteristics.
