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
由於液壓打樁錘液壓系統是一個復雜的非線性系統，本文採用功率鍵合圖法建立液壓打樁錘上行、下降的鍵合圖模型和狀態空間方程，通過四階龍格?庫塔法和預估?校正法相結合編制了模擬程序對狀態空間方程求解，在matlab6 . 5中進行液壓系統的動態模擬，獲得液壓打樁錘運動過程中壓力、位移、速度、加速度等隨時間變化的曲線圖。此曲線圖方便了對液壓系統動態特性分析，為液壓系統的設計和參數優化提供了有益的借鑒。最後，在深入分析雙缸雙作用液壓打樁錘控制系統的功能要求后，採用了以現代計算機技術為基礎的新型工業控制裝置? plc可編程式控制制器，設計出了雙缸雙作用液壓打樁錘的電器控制系統。 -
