摘要
在多学科优化集成软件Isight环境中,综合应用Pro/E参数化建模功能、Abaqus有限元分析功能,建立一种面向塔架门框的CAD/CAE集成优化设计的框架。首先建立门框的参数化几何模型,其次建立有限元分析模型并提交求解。应用试验设计DOE(Design of Experiments)中的最优LHD(Latin Hypercube Design)算法分析门框几何参数因子与应力间的交互效应、相关性。采用模拟退火ASA(Adaptive Simulated Annealing)全局优化算法开展门框的静强度优化设计,以整段塔架的重量最轻为目标,得到满足门框强度设计的最优解。为塔架门框的强度优化设计提供一种科学的设计方法。
In the multidisciplinary optimization ISIGHT software environment,the comprehensive application of PRO / E parametric-modeling function and ABAQUS FEA function establish a framework of CAD / CAE integrated optimization design for tower door. Firstly,the parametric geometric model of door is built,Secondly,the FEA model is established and submitted. The interaction effects and the correlation factor between the geometric parameters and stress are analyzed by the DOE method of optimal LHD algorithm. Static strength optimization design of door is done by the ASA global optimization algorithm. The whole tower weight is as objection,the can strength the optimal design solutions of the door is gotten. The paper provides a scientific design method for strength optimization design of the tower door.
