中文摘要:活塞是贯通式潜孔锤内部的一个重要运动部件,也是产生冲击力、实现冲击碎岩的关键零部件,其受力情况复杂。先对试验生产中破坏的活塞进行有限元分析,找到破坏原因,再通过应力、应变分析优化设计出新活塞。

Numerical Simulation and Optimum Design of Piston in GQ89 DTH Hammer
Abstract:Piston is a moving part of DTH hammer, which produces impact force to realize impacting breaking rock with complicated stress. Firstly, finite element analysis on the old piston that had been broken in the experiment was made with the ANSYS/LS-DYNA program to find out the cause leading to piston’s destruction; then new piston was optimum designed based on the analysis on stress and strain with finite element software.
