活塞和钎杆是液压破碎锤的主要工作部件,在工作过程中,其端部承受剧烈的冲击,因此是液压破碎锤的主要失效部位。本文在建立了液压破碎锤动力学系统的数学模型的基础上,对端部冲击特性进行有限元分析,研究活塞和钎杆的受力特点和规律,对合理确定活塞和钎杆的机械性能、选择材质与热处理工艺,具有一定的意义。
Pistons and drill rod hydraulic hammer is the main working parts, in the course of their work, the end subjected to severe impact, it is the main hydraulic hammer failure. Based on the mathematical model of the dynamic system of the hydraulic breaker, the finite element analysis of the end impact characteristics is carried out to study the force characteristics and rules of the piston and the drill rod. The mechanical properties of the piston and the drill rod are reasonably determined, Choose materials and heat treatment process, has a certain significance.
