摘　　要：在分析了液压冲击器工作原理的基础上,利用一维流体仿真软件FlOWMASTER搭建了气液联合式液压冲击器的仿真模型。结合仿真结果,分析冲击活塞的运动规律以及压力、流量的变化情况,为液压冲击机构的非线性模型研究提供了参考。基于FlOWMASTER的仿真为研究液压冲击器工作机理、提高液压冲击器工作性能和优化系统参数提供了一种可行的理论方法。Based on the analysis of operational principle of hydraulic impactor,the simulation model of gas-liquid united hydraulic impactor was built with one-dimensional fluid simulation software FlOWMASTER.Combining with simulation results,the motion law of impact piston and the changes of pressure and flow rate were analyzed,which provided reference for the research on the nonlinear model of hydraulic impactor.The simulation based on FlOWMASTER provides a feasible theoretical way for studying the working mechanism of hydraulic impactor,improving the working performance of hydraulic impactor and optimizing system parameters.
