The concrete pump truck integrates transportation with pouring process ，which is characterized with flexibility, facility and celerity in civil engineering. As for the concrete pump truck, the arm system is the most important because the rationality of the arm directly influences the performance and pouring position of the truck in its application in civil engineering. For the arm system of the concrete pump truck, the movement of the arm system and the hydraulic cylinder are analyzed respectively with multi-body dynamic theory. By using numerical arithmetic to resolve the dynamic equation, the terminal track of the arms is analyzed. It shows that the kinetic equation built by multi-body dynamics can describe the dynamic characteristics of pump truck exactly.
