摘　　要：对某型挖掘机改装的新型成孔机进行动态性能研究,浅析新型成孔机组成、液压原理及工作原理,建立主阀、动臂液压缸和平衡阀的数学模型,对动臂液压系统进行理论分析。运用AMESim软件建立采用平衡阀方案和液压锁方案的动臂液压系统模型,分析平衡阀和液压锁对新型成孔机动臂下降动态性能的影响。研究表明:采用液压锁方案的动臂下降速度平稳性和快速性均明显优于平衡阀方案。Dynamic performance is studied on a new hole-forming machine modified by a certain type of excavator,and whose forming and hydraulic and working principles are introduced.The mathematical models of main valve,boom hydraulic cylinder and balance valve are established with theoretical analysis on the boom hydraulic system.The hydraulic system model of boom using balance valve scheme and hydraulic lock scheme is established by AMESim software,and the influence of balance valve and hydraulic lock on the dynamic performance of boom falling about the new hole-forming is analyzed.The results show that the falling smoothness and fastness of boom with hydraulic lock is better than that with balance valve.
