Study on Modeling and Simulation of Leg Hydraulic System of Trailer Concrete Pump

Abstract

According to the working principle of leg hydraulic system of a trailer concrete pump, the simulation model of leg hydraulic system is established based on AMESim, and the dynamic characteristics of leg hydraulic system is analyzed. The research result indicates that with the gravity center moves to a leg, the pressure in the corresponding cylinder will increase, and the velocity of the rod will decrease. The greater the gravity center offsets, the greater the influence of the dynamic characteristics. In order to reduce the damage to the leg cylinder, the gravity center and the geometry center should be coincident as much as possible when using a trailer concrete pump.
