基于AMESim的水压凿岩机冲击机构建模与仿真

Modeling and Simulation of the Impact of Institutions of Hydraulic Rock Drill Based on AMESim

本文运用AMESim软件建立水压凿岩机冲击机构的模型;综合考虑各种参数的设置,通过仿真得出活塞和换向阀芯的位移、速度随时间变化的曲线;并且在不同间隙和不同压力的情况下,得出缸体的高压腔到前端开口处的泄漏量。仿真的结论与实验结果基本一致,为水压凿岩机的研究提供了新的理论依据。

This paper builds the model of the impacting body of hydraulic rock drill with AMESim software,obtains curves of the displacement and velocity of the piston and the valve core in considering various parameters,and gets the leakage between the high pressure chamber and the front openings in different gap and different pressure.The simulation results are in agreement with the experimental findings,the research provides a new theoretical basis for the hydraulic rock drill.
