以某大型地下装载机工作装置的动臂为研究目标,寻找轻量化过程中的最优设计。应用ANSYS Workbench软件进行有限元分析,得到应力、变形的分布情况。在此基础之上应用软件中的目标驱动模块,对其进行多目标优化设计,得到最优方案。结果表明,在保证动臂结构强度的基础上,整体质量下降了23.16%,优化效果明显,为装载机工作装置的前期设计提供了依据。 Taking the boom of a large underground loader working device as the research objective, looking for the optimal design in the process of lightweighting. Application of ANSYS Workbench software for finite element analysis, the stress and deformation distribution. Based on this, the target drive module in the software is applied to optimize the multi-objective design and get the optimal solution. The results show that on the basis of ensuring the strength of boom structure, the overall quality is reduced by 23.16% and the optimization effect is obvious, which provides the basis for the preliminary design of loader working device.
