The working principle of hydraulic control system for concrete pump was described firstly. Then we proposed its mathematical model of pumping circuit by means of the power bond graph to dynamically simulate the pumping circuit of hydraulic system with software Matlab/Simulink. We analyzed the outlet pressure of pump and the displacement of rod piston in the different flow ( frequency of pump) and different reversing time. Later we found out that the fundamental cause of hydraulic impact was that the response time of dividing circuit was unmatched with the movement time of the hydraulic cylinders.
