摘要: 针对传统柴油机热力系统建模过程中模块化、可重用性、可扩展性和参数化方面的相对欠缺，从基本物理规律出发详细分析了柴油机各部件数学模型，采用面对对象的陈述式建模语言Modelica，以图形化和模块化的方式在Dymola仿真平台上建立了柴油机各主要部件的模型库，使模型具有很好的扩展性和可重用性。通过对模型进行仿真分析并与实测数据进行对比，结果表明：模型具有较高的精度，基于该模型对柴油机进行性能分析可信度较强。最后，在模型的基础上，分析了不同压缩比和供油提前角对柴油机标定工况下主要性能参数的影响，所得结论具有一定理论和工程实用价值。 In view of the relative lack of modularization, reusability, extensibility and parameterization in the traditional modeling process of the diesel engine, the mathematical model of each component of the diesel engine is analyzed from the basic physical laws. By using the object-oriented modeling language Modelica, the model base of the main components of the diesel engine is built on the Dymola simulation platform in a graphical and modular way. The model has good expansibility and reusability. Through the simulation analysis and comparison with the measured data, the results show that the model has a high precision. The performance analysis of the diesel engine is reliable based on this model. Finally, the effects of different compression ratio and fuel supply advance angle on the main performance parameters of diesel engine are analyzed. The conclusion has a certain theoretical and practical value.
