摘要
以某重点项目的车载一体化配料装置上臂架为研究对象,针对其轻量化、稳定性好、翻转可靠的性能要求,对其进行结构拓扑优化及尺寸优化.根据优化后的结果确定了臂架侧面腹杆以及底面连杆的具体布局和截面尺寸参数,然后把优化结果和实际市场主流尺寸规格相结合重新构建上臂架模型.最后数值分析表明:在保证上臂架力学特性的前提下,该优化方法减重147kg,节约了21%的材料,满足轻量化要求,最大变形量降低6mm,增强了结构的稳定性,最终实现优化的目标.
Abstract
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.
