柴油机船舶推进装置的建模和实时仿真

本文根据准稳态的概念建立了适用于实时仿真的二冲程柴油机船舶推进装置的多阶一性模型。在充分多的试验数据的基础上，结合工作原理建立了各子系统及整个装置的动态模型，这种模型既能反映柴油机内部各参数，精度较高，计算工作量也比较适中。文中提出了一些经验公式，使模拟得以有效地简化。最后，作为实例给出了３５０００吨油船推进装置的实时仿直

Modelling and Real-time Simulation of Marine Diesel Propulsion Plant

Based on the concept of quasi-stable state, a multi-order nonlinear model for real-time simulation of a marine twostroke diesel engine propulsion plant is established and introduced in this paper. With sufficient testing data and working prlnciple, the submodels and the dynamic model of the whole plant are also set up. These kinds of models can demonstrate the internal parameters of the engine with rather high degree of accuracy but reasonable amount of calculating work. Some empirical formulas are given to simplify the model effectively. The real-time simulation of the propulsion plant of a 35,000 ton oil tanker is presented here as an example.
