摘要

液压振动头是声波钻机的核心部件,其液压系统性能的优劣直接影响着声波钻进技术。对液压振动头进行了结构设计及液压系统设计,并建立了液压系统AMESim模型,通过仿真分析寻找液压振动头的振动频率对液压系统性能的影响。仿真结果表明:液压振动头的振动频率f越大,振幅H越小,振动活塞的位移响应近似于正弦曲线,振动活塞的速度、加速度随之增加,振动活塞的激振力F显著增加。
        The hydraulic vibration head is the core component of Sonic drilling rig, and the performance of its hydraulic system influences the technology of sound drilling directly. The structure and hydraulic system of the hydraulic vibration head are designed, and the AMESim model of the hydraulic system is established. The hydraulic vibration system was simulated and analyzed to find out the influence rule of vibration frequency on the system performance. The results show that the larger the vibration frequency f is, the smaller the amplitude H is, and the displacement response of the vibrating piston approximates the sine curve.The velocity and acceleration of the vibrating piston are accordingly increased, and the exciting force F of the vibrating piston is increased significantly.
