Analysis research and optimization of a heavy dump truck body frame

Papers use the software of UG to establish a frame three-dimensional model of a heavy dump truck.And it makes a finite element model of a heavy dump truck frame based on Nastran by the finite element method,such as using the shell unit for meshing and a reasonable simplification and connections.It just researches on the stiffness and strength of the frame by applying the corresponding boundary conditions and load conditions in only bending or torsion to get stress-strain diagram,and finds and improves the weak parts of the frame structure.The theoretical proof was got by the comparation of structures optimization.
