摘要
通过对无阀液压凿岩机运动和动力过程的分析 ,列出了无阀液压凿岩机前后腔进排油条件 ,建立了无阀液压凿岩机活塞运动的微分方程。并用MATLAB进行了计算机仿真 ,结果表明 。
Through analysis the dynamics process of the valveless hydraulic rock drill, the conditions of inlet and outlet oil around the chamber have been deviated and the movement equation of the piston has been set up.The computer simulation program has been compiled.The calculating results indicate that the program can be used to design and improve the valveless hydraulic rock drill.
