Lightweight Design of Dump Truck Frame Based on Finite Element Method

摘要

With the gradual enhancement of people's awareness of environmental protection, the demand for energy saving and emission reduction of dump trucks is getting higher and higher. In this paper, the finite element analysis software is used to simulate and analyze the two working conditions of a certain type of dump track frame with greater damage. The simulation results show that the strength and stiffness meet the normal working requirements. Based on this, the lightweight design of the frame is carried out. A new material high strength steel A610L, is selected to optimize the thickness of the original frame according to the thin shell theory. Then the frame is re-modeled and simulated again under different working conditions. The strength and stiffness of the optimized frame meet the design requirements. After optimization, the weight of the dump truck frame is reduced by 9.47%, the toxic gas in the exhaust is reduced by 4.5%, and the fuel consumption is reduced by 8%.
