多腔体液压缸设计优化
Design Optimization of Multi-chamber Hydraulic Cylinder
摘要
Abstract
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.关键词
