摘　　要：以某型号液压破碎锤为研究对象,分析其工作原理,并通过UG NX建立破碎锤的三维模型。利用多体动力学软件RecurDyn和控制软件Simulink,实现了液压破碎锤机械系统和控制系统的联合仿真,获得破碎锤活塞和钎杆的运动参数,以及活塞、钎杆和钎杆销的载荷历程。仿真结果符合厂家提供的参数要求。另外,利用压力测试法对液压破碎锤进行测试。测试结果表明,活塞速度的仿真值与测量值的误差为11.2%,冲击能的误差为5.39%。联合仿真结果可为液压破碎锤的优化和新产品的开发提供参考。The working principle of a certain hydraulic breaking hammer was analyzed, and its 3D model was built by UG NX. In addition, RecurDyn and Simulik were appfied to conduct the co-simulation of the mechanical system and the control system of the hydraulic breaking hammer, and the dynamic parameters of piston and drill rod as well as the loading course of piston, drill rod and drill rod pin were obtained. The simulation results showed the parameters were all within the range provided by manufacturer. Moreover, pressure testing method was applied to test the hydraulic breaking hammer. The test results showed that the error between simulated piston velocity and measured one was 11.2% and the error of impact energy was 5.39%. The co-simulation results offered references for optimization and development of the hydraulic breaking hammer.
