摘　　要：应用键合图理论研究了船用蒸汽动力装置冷凝系统的仿真建模.以规范化的方式统一分析了系统中同时存在的机液能量转换、热功转换以及热传递和质量迁移等多种能量作用,从基本物理规律出发建立了其通用仿真数学建模,并结合具体算例进行验证.通过仿真结果与实测值比较,证明所建立的模型能够真实地反映实际对象的静态与动态工作特性,并具有较好的精确性和实时性,所得结论具有一定的理论和工程实用价值.The modeling and simulation of a condensation system in marine steam power plant were studied by the bond-graph theory.The coexistent mechanical power conversion,heat and mass transfer in the system were analyzed by standard method,and its universal model on the basic physical laws was established.Using practical object to validate the bond-graph model,it is found that the model can preferably respond the static precision and dynamic characteristics of marine steam turbine and has preferable accuracy and（real-time） characteristic,the conclusions have some theoretic and practical value.
