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。
Taking a certain type of hydraulic breaker as the research object, the working principle is analyzed and a three-dimensional model of the breaker is established by UG NX. The multi-body dynamics software RecurDyn and control software Simulink are used to realize the joint simulation of the mechanical system and control system of the hydraulic breaker. The movement parameters of the piston and drill rod of the hammer and the load history of the piston, drill rod and drill rod pin are obtained. Simulation results in line with the parameters provided by the manufacturer. In addition, the use of pressure test hydraulic hammer test. The test results show that the error between the simulation value of the piston speed and the measured value is 11.2% and the impact energy error is 5.39%. The joint simulation results can provide reference for the optimization of hydraulic breaker and the development of new products.
