The precast concrete component group vertical mold forming machine(referred to as the group vertical mold)is a new type of equipment for producing precast concrete components.In order to improve the vibration effect and load-bearing capacity of the group standing mold table,it takes the group standing mold template structure as the research object,and proposes an optimi-zation design theory combining the emerging design of topology optimization and the response surface method.First,based on the variable-density method,the topological optimization design of the layout of the ribs of the group standing formwork structure was carried out,and the best material distribution form of the reinforcing ribs was obtained,and the formwork structure of the group standing formwork was redesigned.In order to obtain the best design parameters of stiffeners,a central composite test design was adopted to establish a response surface model of the maximum displacement and maximum equivalent stress of the template structure.Multi-objective genetic algorithm is used to optimize the response surface model,and the optimal combination plan of the parameters of the reinforcing rib is obtained.The results of finite element analysis show that compared with the initial scheme,the optimized design plan improves the rigidity and strength of the table,at the same time improves the vibration characteristics of the formwork structure,and improves the molding quality of the precast concrete components.This research provides theoretical guidance for further advancing the research of group vertical mold.
