在查阅大量文献的基础上,对凿岩机、冲击器等冲击机械的活塞应力与强度研究现状进行了分析,总结出目前的研究主要有应用一维波动力学理论对冲击机械的活塞进行强度分析、应用有限元软件对冲击机械活塞进行强度分析、分析活塞失效机理,从设计选材及热处理方面提高活塞强度的方法三种类型。
On the basis of consulting a large number of literatures, the research status of piston stress and strength of percussion machinery such as rock drill and impactor is analyzed. At present, the current research mainly includes the application of one-dimensional wave mechanics theory to analyze the strength of piston of impact machinery. The finite element software analyzes the strength of the impact mechanical piston, analyzes the failure mechanism of the piston, and presents three methods to improve the piston strength from the aspects of material selection and heat treatment.
