Research on Optimal Design of Upper Boom Structure of Vehicle-Eounted Integrated Batching Device
Taking the upper arm of the on-board integrated batching device of a key project as the research object,the structure to-pology optimization and size optimization were carried out according to the performance requirements of its lightweight,good sta-bility and reliable turnover.According to the optimized results,the specific layout and sectional size parameters of the side belly bar and the bottom connecting rod ofthe boom were determined.Then,the upper boom model was reconstructed by combining the opti-mized results with the actual mainstream size specifications.Finally,the numerical analysis shows that under the premise of ensur-ing the mechanical properties of the upper arm,the optimization method reduces the weight by 147kg,saves the material by 21%,meets the lightweight requirements,reduces the maximum defomation by 6mm,enhances the stability of the structure,and finally achieves the optimization goal.
