Lightweight design of center turntable of tower stereo garage based on differential evolutionary algorithm

In order to reduce the weight of the rotating carrying device of the tower garage to improve the stability performance of the lifting system, the lightweighting method of the center turntable of the tower garage based on differential evolution algorithm is proposed. Taking the center turntable of a tower garage as the research object, the center turntable is subjected to static analysis, and 160 sets of data are obtained by using the optimal Latin superlattice method to optimize the support vector machine through the particle swarm optimization algorithm to carry out the model training; finally, the predicted data of the model is used in combination with the differential evolution algorithm to find out the best combination of the design variables and round up to obtain the optimal solution. The results show that the maximum deformation and the maximum stress after optimization are within the specified range, and the weight reduction of the final model is 5.26%, which is of great significance for the further research of tower garage.
