多腔体液压缸设计优化OA
Design Optimization of Multi-chamber Hydraulic Cylinder
为了进一步降低液压挖掘机动臂多腔体液压缸驱动系统能耗,并对多腔体液压缸进行轻量化设计,首先探明了多腔体液压缸面积比对系统能耗的影响,进一步采用非支配排序遗传算法Ⅱ对多腔体液压缸的关键结构参数进行优化.结果表明,当多腔体液压缸无杆腔与储能腔的面积比达到 1.0～1.1 时,挖掘机动臂一个工作循环内能耗达到最低水平;经非支配排序遗传算法Ⅱ优化结构参数的多腔体液压缸,最大应力降低35.16%,整体重量减轻21.72%;挖掘机动臂一个工作循环内系能耗相比优化前降低7.31%.
We try to further reduce the energy consumption of the boom system driven by a multi-chamber hydraulic cylinder in hydraulic excavators,while also achieving a lightweight design of the cylinder.The effect of the area ratio on system energy consumption is first investigated.Then,the Non-dominated Sorting Genetic Algorithm Ⅱ is used to optimize the key structural parameters.The results show that when the area ratio of the rodless chamber to the energy storage chamber is between 1.0 and 1.1,the energy consumption of the excavator boom over one working cycle is the lowest.After optimization,the maximum stress of the multi-chamber hydraulic cylinder drops by 35.16%,and the overall weight decreases by 21.72%.In addition,the energy consumption per working cycle is reduced by 7.31%compared with that before optimization.
