【摘要】 活塞的运动是水下液压冲击器功能实现的关键,利用"龙格-库塔方法"对活塞杆的动力学方程进行进行理论分析分析,从而建立起时间与行程的关系拟合曲线,再结合配油阀阀芯的运动进行仿真分析,对设计合理性进行了进一步的验证.也为此方面知识的研究提供了分析方法.更多还原

【Abstract】 The movement of the piston is a key feature of underwater hydraulic impactor implemented. It is necessary to analyze its theory. The Runge- Kutta method of dynamic equations was used to analyze the movement of the spool valve of the piston rod. in order to establish relations with the travel time curve fitting.更多还原
