【摘要】 针对活塞前腔常高压外控柱状滑阀型液压凿岩机,设计成一个计算机仿真程序系统,直观地显现液压凿岩机的内部工作状态。研究结果表明,仿真分析与实测结果相吻合,完全适用于对液压凿岩机进行辅助设计和理论分析。更多还原

【Abstract】 A computer simulation program has been written aiming at hydraulic rock drill with constantly pressurized front chamber of piston and externally controlled cylindrical spool. It produces direct display of the operation inside a hydraulic rock drill.The research shows that the simulation results coincide with the experimental ones and the program is readily applicable to computeraided engineering of hydraulic rock drills as well as their theoretical analysis.更多还原
