摘要
提出了复杂产品优化的2种模式,总结了多学科虚拟样机优化的支撑环境应具备的特征,重点介绍了多学科虚拟样机建模、仿真与优化平台COSIM(collaborative simulation)。归纳了COSIM平台集成CAX/DFX工具的主要方法,总结了多学科虚拟样机优化的特点。重点分析了MDF方法的特性,在此基础上,提出了一种改进的MDF多学科虚拟样机框架。针对起竖系统设计,开展了起竖系统多学科虚拟样机优化。
Two types of optimization of complex products are proposed. Characteristics of supporting environment of multidisciplinary virtual prototype optimization （MVPO） are summarized. Modeling, simulation and optimization platform of muhidisciplinary virtual prototype, collaborative simulation （COSIM） is expounded. The main methods of integration of COSIM collaborative simulation platform, CAx/DFx tools and characteristics of MVPO are summarized. The characteristics of MDF are analyzed. On this basis, a new framework of MVPO, advanced MDF, is proposed. Finally, the specific procedures of MVPO of the erecting system and the optimization results are presented.
