| 摘 要： | 钻探机具由于其恶劣的工作环境和复杂的受力情况，应用有限元分析方法可实现它的数值模拟，且具有明显的优越性。运用ANSYS有限元软件对GQ－160型风动冲击器活塞的应力应变进行了分析，得出活塞的变形不影响工作，应力集中部位与实际情况相符合的分析结果，说明应用有限元法对钻探机具进行分析是准确可靠的。

| Abstract: | Because of its bad working environment and complex force, the drilling tools can be simulated by the finite element method (FEM). It is advantage that FEM can be used to analyze drilling tools. The stress and strain of the piston of GQ 160 type air driven DTH hammer are analyzed by using ANSYS software. Conclusions are that the deformation of the piston doesn't effect the work of the DTH hammer and the location of stress concentration accords with fact condition, which shows that it is very accurate and reliable to analyze drilling tools by using FEM. |
