摘　　要：本文主要介绍了作者应用键图法建立的一台大型船用锅炉和一台四冲程中速船用柴油机的非线性数学模型。文章着重分析了建模机理,并阐明了建模过程中存在的有关问题和解决这些问题的有效措施,最后还给出了对所述动力系统的动态分析和控制系统设计颇有价值的数字仿真结果。Two typical marine dynamic systems are modellea using pseudo bond graph in this paper to show the usefulness of the technique, the difficulties encountered, and the ways and means by which more realistic models can be obtained. A large marine boiler and a four stroke marine diesel engine are taken as the objects of research for which the non-linear mathematical models are formulated. Modelling philosophy is emphasized and simulation results which are valuable for the dynamic analysis of power system and the design of control systems are discussed in some details.
