摘　　要：以声波钻进液压振动头为研究对象,利用AMESim软件对液压振动系统进行了建模和仿真分析,探讨了系统压力、供油流量对液压振动系统各参数的影响规律,并对液压振动系统的泄漏进行了分析。结果表明;振动活塞的振幅、速度随着系统压力和供油流量的增加而增大,且振动活塞的振幅近似呈线性增加;间隙越大,泄漏越严重,并且间隙的大小对泄漏量影响较为显著;密封长度越大,泄漏越小;系统压力越大,泄漏量也增加。By taking a sonic drilling hydraulic vibration head as research object,the hydraulic vibration system was modeled and analyzed with simulation by using the AMESim software. The effect laws of system pressure and oil flow to every parameters of hydraulic vibration system were explored,and the leakage of hydraulic vibration system was analyzed. The results show that amplitude and speed of the vibrating piston are increased along with increasing of system pressure and fuel flow,and the amplitude increased approximately linearly. The greater the gap,the more serious is leakage,and the effects of gap size on the leakage are more significant. Sealing length is larger,the smaller leakage is. The system pressure is bigger,and then the amount of leakage is also increased.
