Simulation and Topological Optimization of the Lifting Mechanism of a Dump Truck

Abstract:

Taking a heavy dump truck as the research object, multi-body analysis and movement simulation are carried out on the lifting mechanism to determine the largest lifting time of the hydraulic cylinder. The stress value of key components and corresponding lifting Angle are acquired, and the calculated results and the actually known parameters and data are compared to verify the rationality of the design of lifting mechanism. Using ABAQUS for the strength check of the triangular arm and using OptiStruct for the topology optimization of the part, the mass and the volume of the new part are reduced more than 1 time. The development of part can improve product quality, shorten development cycle and reduce costs. Key words: Lifting Mechanism, Simulation, Strength Check, Topology Optimization
