摘　　要：混凝土预制构件成组立模成型机(简称成组立模)是一种新型的生产混凝土预制构件的设备。为了提高成组立模台面的振动效果和承载能力,本研究以成组立模模板结构为研究对象,提出了一种拓扑优化新兴设计与响应面法结合的优化设计理论。首先,基于变密度法对成组立模模板结构加强筋布局进行拓扑优化设计,得到了加强筋最佳的材料分布形式,以此对成组立模模板结构进行了结构优化设计。为得到最佳的加强筋设计参数,采用中心组合试验设计,建立模板结构最大位移、最大等效应力的响应面模型。利用多目标遗传算法对响应面模型进行优化求解,得出加强筋各参数最优的组合方案。有限元分析结果表明:与初始方案相比,优化设计方案提高了台面的刚度和强度,同时改善了模板结构的振动特性,并提高了混凝土预制构件的成型质量。该研究为进一步推进成组立模的研究提供了理论指导。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.
