中文摘要： 本项目主要研究在多领域统一框架下，复杂机电产品仿真优化模型统一约束表达及求解过程中的关键理论。在研究复杂机电产品的设计和分析过程的基础上，采用统一约束的复杂系统建模方法，针对多领域物理系统，分别建立机械、电子、液压、控制等领域系统的模型单元库，利用物理-数学模型的映射机制，建立复杂机电产品多领域仿真优化模型；研究复杂系统多领域约束模型的耦合关系，对统一约束表达模型进行参数灵敏度分析并缩小约束规模；采用全局综合满意度尽量大的原则，实现基于部件级多领域约束协调，并用同伦迭代法对处理后的大规模多领域统一仿真优化模型进行求解，从而为复杂机电产品的CAD/CAE创新设计奠定共性理论基础，并提供关键的使能技术。

英文摘要： This project is mainly discussed in areas under a unified multi-domain framework, For complex products, the unified constraint expression of simulation optimization model and critical theory in the process of solving. On the basis of studying the design and analysis process of complex products, using the unified constraint modeling methods of complex systems, for multi-domain physical systems, establish its mechanical, electronic, hydraulic and control system model cell library respectively, using the physical-mathematical model mapping mechanism, the multi-domain simulation optimization model of complex product is established; study the complex coupling between multi-domain constraint model of the system, analyze the parameters sensitivity of unified constraint expression model and reduce the restraint scale; Using the principle of global satisfaction as far as possible, to achieve coordination of multi-domain constraints based on the component level, solving the Large-scale multi-domain unified simulation optimization model with the homotopy iteration method, in order to lay a common theoretical basis for the CAD / CAE innovative design of complex products, and provide the critical enabling technology.
