摘　　要：根据工厂实际需要,把立式压罩机主机架由四立柱结构改为C框架结构,采用有限元分析软件ABAQUS对该结构进行了弹塑性分析,得出了圆弧拉筋半径、压板厚度、侧板高度和侧板间距对结构的水平、竖直方向最大位移和最大等效应力的影响规律;并在此基础上,采用MATLAB神经网络工具箱对C框架结构进行了优化设计,得出了符合用户要求的C框架结构,这对压装结构设计优化有一定的指导作用.According to actual needs, the four-column vertical press-assemblage machine of sealed cowlings structure is changed into C-shaped frame structure for a Using finite element analysis software ABAQUS, the elastic and plastic finite element analysis of the C-shaped frame structure is performed. The effect regulations of circular reinforcement radius, clamp thickness, curb height and curb space on the maximum horizontal and vertical displacements are obtained. The optimization design of the C-shaped frame structure is implemented using neural network of MATLAB toolbox. The optimization scheme of the C-shaped frame structure is obtained which accords with the requests of the users.
