摘要
针对装载机动臂结构笨重、主要板件厚度存在冗余等现象,在不改变动臂结构的安装尺寸并满足动臂刚度和强度的前提下,对动臂结构进行多种工况下的参数优化设计。依据优化后的结果建立动臂结构新模型进行有限元静力学分析,对比分析结果,验证了动臂结构的刚度和强度满足工作需求,实现动臂减重约4.48%,节约原材料成本303.91元/台(套)。
In this paper, parameter optimizations in different working state of the boom structure have been carried out under the conditions of unchanged installation size, stiffness and strength of the boom structure, aiming at optimizing bulky structure of the loader boom and redundancy of the main board in thickness. According to the optimization result, the new model of the boom structure was established and the finite element statics analysis was carried out. Compared with the analysis results,the stiffness and strength of the new boom structure can meet the work demand; the weight reduces about 4.48%;and the cost saving of the raw material is about 303.91 RMB per loader.
