摘要
利用阻抗消声原理为气动凿岩机设计了一种新型的消声罩。本消声罩具有良好的声学性能及流体力学性能 ,同时又具有重量轻、安装方便等特点 ,且能降低工作面的空气污染。
This paper designed a new type of muffler for pneumatic rock drill with the theory of impedance.The type has excelent acoustic and hydromechanics function,its weight is lighter,and it can be conveniently installed on pneumatic rock drill and reduce the air polution of working surface as well.
