摘要

通过改变铝钢爆炸焊接复合材料铝板的厚度

研究了其对阻尼性能的影响。结果表明

随铝板厚度的增加

传递函数存在明显的相位差

振幅明显降低

内耗增加

固有频率下降 ;对铝钢爆炸焊接复合材料的强迫振动测试表明

为充分发挥此材料的阻尼性能

应在频率高于 170Hz或低于 5 0Hz时使用

Abstract

The damping properties of Al-steel explosive welding compound materials with different thickness were investigated.The results showed that the transmission function has an obvious phasic difference

the amplitude significantly decrease

the internal friction increases

and the instrinsic frequency decreases with the thickness increase of the Al plate.The forced vibrating testing showed that the proper frequency is over 170 Hz or below 50 Hz.
