Abstract：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.
