摘要
针对管缆自动伸缩装置工作过程中的一些不稳定因素,如液压缸支架与车架在工作过程中易发生变形等问题,进行了优化设计。对管缆自动伸缩装置进行静力学分析,并基于Workbench对液压缸支架以及车架进行有限元分析,采用模态分析对建立的模型进行验证,对有限元分析的结果进行优化设计,将模型参数化,对设计变量进行灵敏度分析,使用拉丁超立方抽样法取点,通过多目标优化遗传算法(Multi-Objective Optimization Genetic Algorithm,MOGA)对多目标函数进行优化求解,随后对比初始数据与优化结果。结果表明,优化后,在质量减轻的情况下,液压缸支架的最大等效应力以及最大变形量分别降低了24.95%和19.03%;车架的最大变形量增加了26%,最大应力降低了42%,有效地提高了管缆自动伸缩装置的稳定运行。
In view of some unstable factors in the working process of automatic expansion device of cables,such as the hydraulic cylinder support and frame were easy to deform,the optimization design was carried out.Static analysis of the automatic expansion device of the cable,finite element analysis of the hydraulic cylinder support and frame based on Workbench were carried out,the modal analysis was used to verify the establishment model,the optimization design of the finite element analysis results was carried out,the model parameterization,the design variables sensitivity analysis were carried out,and the Latin hypercube sampling method was used to pick points.The multi-objective function was optimized by multi-objective optimization genetic algorithm(MOGA),and then the initial data was compared with the optimization results.The results show that the maximum equivalent stress and maximum deformation of hydraulic cylinder support is reduced by 24.95%and 19.03%respectively under mass reduction conditions.The maximum deformation of the frame is increased by 26%,and the maximum stress is reduced by 42%,which effectively improves the stable operation of the automatic expansion device.
