| 摘 要： | 以自行研发的后控式SYYG65型水力凿岩机冲击系统为研究对象,在Matlab中应用SimHydraulics工具箱,建立水力凿岩机冲击系统动态仿真模型,实现流体/机械的混合仿真.建模过程不考虑系统运行状态的转换,简单有效地实现了活塞和阀芯在水压力作用下的耦合计算.在泵供水流量为120 L/min,减压阀卸荷压力为16 MPa时,对系统进行仿真计算,获得了在此条件下冲击机构运动与活塞前后腔压力变化典型曲线,并与实测结果进行比较.同时,运用这一动态仿真模型对蓄能器参数进行优化计算.研究结果表明:在有效容积为0.24～0.27 L和充气压力为5.00～5.75 MPa的最优工作参数下,SYYG65型水力凿岩机冲击系统能量利用率有显著提高.该SimHydraulics仿真模型对水力凿岩机冲击系统参数设计和优化匹配研究是有效的.

| Abstract: | The dynamical simulation model of water-powered percussive rock drilling system was built by SimHydraulics toolbox of Matlab code,based on the self-researched SYYG65 rock drilling system.And then the fluid/mechanical hybrid simulation was realized.The simple and effective coupling calculation of piston and the valve core under the water pressure was carried out by avoiding the transition of the running state of the system.With the 120 L/min in pump water supply and 16 MPa in unloading pressure,the typical c... |
