摘　　要：设计液压钻井泵的关键是分析液压系统的动态特性。针对钻井泵液压系统应用系统协同仿真软件AMESim建立了液压系统仿真模型,并分析了钻井泵液压系统的各种工作状态,确定了最佳匹配参数,使得系统和液压元件的设计缺陷在物理成型前就得到优化。结果表明,应用该方案可以使钻井泵流量稳定,无脉动;通过AMESim仿真模型验证本方案在设计布置3个泵缸活塞初始位置、调节缸速比为2时能达到预期目标;为了保证3个活塞缸的协调运动,必须合理地设计开环增益,通过不断验证,找到一个合理的数值。The key to the design of hydraulic drilling pump is the analysis of the dynamic characteristics of the hydraulic system. Applying the simulation software of systematic synergism named AMESim,the simulation model of the hydraulic system has been established for the hydraulic system of drilling pump and the optimum matching parameters have been determined,achieving the optimization of the defect in the design of the system and hydraulic elements before the physical shaping. The results show that application of this plan can achieve the flow stability of the drilling pump and avoid fluctuation. The AMESim simulation model experiment indicates that the plan can arrive at the expected goal when the initial position of three pump cylinder pistons has been determined and the cylinder transmission ratio is two. To ensure the coordinated movement of the three piston cylinders,the open-loop gain must be designed reasonably and a reasonable digital value must be obtained by repeated experiments.
