摘　　要：现代工程系统往往是以复杂结构/机械系统为主体,融合热、流、电磁等若干子系统的多场耦合系统.此类系统动力学建模复杂、计算难度大,给系统动态特性高效精确评估与设计优化带来前所未有的挑战,有关其高效精确动力学仿真方法的研究愈发受到关注.本文详细回顾了复杂工程系统多场耦合动力学仿真方法研究成果和进展,包括:多场耦合动力学建模与数值求解基本策略、网格变形处理方法、耦合数据交换技术、数值计算效率等问题,在此基础上详细讨论了单一和混合不确定性条件下多场耦合系统不确定性分析及可靠性评估方法,以期为相关研究提供有益的借鉴和参考.Modern engineering system is usually a multi-field coupling system with complex structure/mechanical system as the main body,which integrates thermal,electromagnetic,fluid and other subsystems.The dynamics modeling of these systems are complex and their numerical calculate are also difficult,which bring unprecedented challenges to the efficient and accurate evaluation and design optimization of the system dynamic characteristics.In this paper,the research progress of multi-field coupling dynamics simulation methods for complex engineering systems are reviewed in detail,including the basic strategies of multi-field coupling dynamics modeling and numerical solution,mesh deformation processing method,coupling data exchange technology,numerical calculation efficiency,etc.On this basis,for uncertain multi-field coupling engineering systems,their uncertainty analysis and reliability evaluation methods under single and hybrid uncertainties are discussed in detail.This review paper is expected to provide some useful references for related researchers.
