The Weight Reduction Optimization Design of Rope Clip Based on Surrogate Model
As the core part of aerial ropeway,the rope clip has the characteristics of special working environment and complicated working conditions,so there are few researches on its structure optimization at home and abroad.On the other hand,the tradi-tional finite element optimization methods for high-dimensional problems are often inefficient and inconvenient to be applied in engineering.A high-precision Kriging surrogate model is constructed for weight reduction optimization and an MIGA-NLPQL algorithm is used to obtain the global optimal solution.The results show that the structure weight is reduced by 22.05%on the premise of guaranteeing strength and non-resonance,and the maximum relative error between Kriging model and finite element model is5.27%.The practicability of the high precision surrogate model in engineering optimization is verified.
