摘要
实验分别采用铝片作为波形整形器和橡胶胶片作为软性介质,通过SHPB冲击实验研究了2种方法对改善加载波波形的效果影响.实验表明这2种方法都可以有效改善加载波的波形,减小和消除应力波的弥散效应.从加载波波形上来看,铝片的效果要优于橡胶胶片.
Aluminium sheet is adopted as the pulse reshaper and rubber sheet as a flexible medium respectively in this paper to improve the wave shape of carrier wave. SHPB impact loading experiment is carried out to study the impact. It is shown through the experiment that the two methods are both effective in improving carrier wave shaper and minishing dispersion behavior of stress wave. The effect of aluminium sheet is better than that of the rubber sheet from the shape of carrier wave.
