Lightweight Design of Loader Rocker Arm Based on Structural Optimization

To enhance the structural efficiency and economy of the loader arm, this study, based on the structural optimization method and aiming at lightweighting, conducts multi-objective topology optimization design of the loader arm using Altair Inspire software.The research verifies the effectiveness of topology optimization technology in the lightweight design of the loader arm, significantly reducing manufacturing costs and fuel consumption, and providing a replicable technical path for the engineering optimization of complex structures.Through static analysis, modal analysis and multi-body dynamics simulation, the load conditions and mechanical characteristics of the bracket are clarified.By comparing different shape control schemes and model reconstruction methods, the optimal design scheme is selected.The results show that the weight of the optimized bracket is reduced by 22.89 %, and the minimum safety factor is 1.9, both meeting the design standards.
