摘　　要：从基本物理规律出发,应用键合图理论研究了船用蒸汽轮机的仿真建模问题,以规范化的方式统一分析了汽轮机装置中同时存在的热功转换、热传递和质量迁移3种能量作用,建立了一类具有通用性的船用汽轮机装置全工况键合图模型。结合具体算例对模型进行验证,通过仿真结果与实测值比较证明模型能够真实地反映船用汽轮机装置的静态与动态工作特性,具有较好的精确性和实时性。对键合图理论在热工对象仿真建模领域内的应用作了一些探讨,所得结论具有一定的理论和工程实用价值。The modeling and simulation of marine steam turbine was studied by the bond-graph theory.Paper analyzed the coexistent mechanical power conversion,heat and mass transfer in steam turbine plant by standard method,and established a universal full-range bond-graph model of marine steam turbine based on the basic physical laws.Using practical object to validate the given model,found it can preferably respond the static precision and dynamic characteristics of marine steam turbine,has preferable accuracy and real-time characteristic.Paper also probed into the application of bond-graph theory in the modeling and simulation of thermal objects,the conclusions have some theoretic and practical value.
