柴油机热工故障仿真研究

A Study of Simulation of Abnormal Performance in Diesel Engine

运用结构模型和功能模型对柴油机热工故障作了简要的分析 ,建立了一个较通用的柴油机热工故障的仿真模型 ;开发了柴油机热工故障仿真软件 ,并对柴油机典型热工故障在不同故障严重程度下进行仿真计算 ;对仿真结果进行分析 ,揭示了柴油机热工故障与热工参数之间的内在联系 。

This paper analyzes abnormal performance in diesel engines according to engine structure model and function model. A faults simulation software has been also developed, which can simulate fifteen kinds of typical malfunctions under different grades. The results of simulation indicates the inner relations between engine malfunctions and abnormal thermal parameters, thus provides useful reference for faults diagnosis.
