Structural Design of Variable Cross-Section Casting Boom Based on Topology Optimization
The study found that the traditional plate boom of the loader has a greater degree of strength and material redundan-cy.In this paper,a 5t loader is used as the carrier,and the boom is optimized in terms of weight reduction.Combining the basic principles of structural topology optimization.Based on the finite element analysis and topology optimization of the original boom,a new type of variable cross-section casting type loading mobile boom structure is proposed and designed.Use Ansysto ver-ify the finite element strength of the optimized boom.And verify the correctness of the simulation model through stress and strain experiments.Simulation and experimental results show that under the conditions of structural rigidity and strength.The weight of the boom is reduced by19.7%compared with the1035kgbefore the optimization,achieving the goal of lightweight.
