摘　　要：高效精密化、智能集成化、虚拟数字化是现代产品设计的发展方向。提出了一种将多学科设计优化方法融于产品的数字化设计过程,智能集成化设计复杂产品数字化功能样机的多学科综合设计模式。针对汽车实例,构建了多学科自动化设计优化平台,给出了集成优化分析流程,实现了多性能集成全分析与优化仿真,基于整车虚拟测试,验证了该模式的有效可行性。Efficient, precise, intelligent, integrated, virtual and digital is the design trend of modern complex product.A multidiscipline integrated design method was proposed, which takes functional digital prototype （FDP） as the core to integrate multidisciplinary design optimization （MDO） into digital design process. The MDO integration platform was constructed to realize the automated multidisciplinary design process efficiently and intelligently. Full analysis of product multiperformance and optimized simulation can be executed through integrated analyzing flow of vehicle engineering design. The proposed approach was also demonstrated by whole vehicle virtual testing. It can be adopted to the other complex system.
