Power bond graph is used to established the bond graph model of the lifting and dropping of hydraulic pile hammer and state space equation in the paper for hydraulic pile hammer is perplexing nonlinear system . in order to attain the graph that pressure , position , velocity , acceleration vary with time in the course of driving pile simulation procedure solving state space equation is designed on the basis of combining four - order runge - kutta method with predicator - corrector method , dynamic simulation of the hydraulic system is studied in matlab 6 . 5 . it is convenient to analyse dynamic characteristics of the hydraulic syste m , beneficial to the design and parameter optimization of the hydraulic system . in the final part of the paper , under detailed analysis of the control characteristics for double - acting hydraulic pile hammer with double cylinders , control system based on the programmable logic controllers founded on technology of modern compute is designed
由于液压打桩锤液压系统是一个复杂的非线性系统，本文采用功率键合图法建立液压打桩锤上行、下降的键合图模型和状态空间方程，通过四阶龙格?库塔法和预估?校正法相结合编制了仿真程序对状态空间方程求解，在matlab6 . 5中进行液压系统的动态仿真，获得液压打桩锤运动过程中压力、位移、速度、加速度等随时间变化的曲线图。此曲线图方便了对液压系统动态特性分析，为液压系统的设计和参数优化提供了有益的借鉴。最后，在深入分析双缸双作用液压打桩锤控制系统的功能要求后，采用了以现代计算机技术为基础的新型工业控制装置? plc可编程控制器，设计出了双缸双作用液压打桩锤的电器控制系统。
