基于ANSYS装载机摇臂仿真分析与轻量化设计

Simulation Analysis and Lightweight Design of Rocker Arm of Loader Based on ANSYS

将装载机摇臂的初始CREO三维模型导入到仿真分析软件ANSYS Workbench中对最大崛起力工况下的静态结构进行仿真分析,得到其等效应力云图及总变形云图。根据仿真结果对原摇臂模型进行结构优化以及轻量化设计。对改进后的摇臂做最大崛起力工况下的静态结构仿真分析,并与原模型进行分析对比。分析结果表明:优化后的摇臂最大应力下降16.6%,风险点平均应力下降21%,整体质量减轻14.1%,符合预期效果。

The initial CREO three-dimensional model of the loader rocker arm is imported into the simulation analysis software ANSYS Workbench to perform the static structure simulation analysis under the maximum rising force condition,and the equivalent stress cloud diagram and the total deformation cloud diagram are obtained.According to the simulation results,the original rocker arm model is optimized for structure and lightweight design.The static structure simulation analysis of the improved rocker arm under the maximum rising force condition is performed,and the analysis is compared with the original model.The analysis results show that the maximum stress of the optimized rocker arm is reduced by 16.6%,the average stress at risk points is reduced by 21%,and the overall mass is reduced by 14.1%,which is in line with the expected effect.
