摘　　要：针对典型门窗中挺型材,利用ANSYS/APDL命令流开展结构参数化建模,采用响应面法获得型材结构参数与力学性能指标的数学关系,以减轻结构自重为优化目标,建立了型材优化设计数学模型,采用遗传算法对优化模型进行了寻优计算,并对某断桥中挺型材开展了优化设计,结果显示模型具有良好的优化效果。Parameterized finite element analysis model was obtained,with the ANSYS/APDL command stream,for the aluminum profile on windows.To obtain the relations between the stuctural parameters and the mechanical response,the RSM was introduced.The optimal design model has been developed,taking structural weight as an optimization objective,with genetic algorithm used to computing the model.The optimal design of the profile about a broken bridge were then carried out,while results show that the model has good optimization ability.
