Strength analysis and structural parameters optimization of the boom system of the truck-mounted concrete pump

Some parts such as boom, cylinder lug and connecting rod of the boom system of the truck-mounted concrete pump are easily broken because of the complex structures and various working conditions of system. Therefore, this paper makes the finite element model with the software of HyperMesh and Ansys based on an existing Proe model of the boom system, and then does the strength calculation. The stress distributing status and dangerous sections of the boom system are found out from this. The relations between the structural parameters and the structural strength are studied with the FEM for the fragile parts, and the optimized schemes are put forward. Also, the structural improvement and parametric optimization of a common connecting rod of the truck-mounted concrete pump are made, which provides a reference for the design of the connecting rod.
