摘要
建立了一个涡轮增压柴油机动态过程实时仿真的准稳态非线性模型．该模型基于柴油机稳态试验数据建立动态模型，按时间尺度原则，只考虑柴油机状态量的时间平均效应，忽略循环波动，突出实时性．详细描述了柴油机、增压器的热力学及动力学模型．以内燃机车用１６Ｖ２４０ＺＪＤ柴油机为仿真对象，在ＭＡＴＬＡＢ／ＳＩＭＵＬＩＮＫ环境下进行了动态过程实时仿真，并给出了典型稳态及动态过程的仿真结果．
A quasi steady nonlinear dynamic simulation model of turbocharged and intercooled diesel engine based on steady experimental results is developed.According to the principle of time scale,the mean time effect of engine state is considered.The cycle fluctuation is neglected and the real time characteristic of engine is stressed.The thermodynamic and dynamic sub models of diesel engine and turbocharger are described in detail.The dynamic simulation of locomotive 16V240ZJD turbocharged diesel engine is made in the environment of MATLAB/SIMULINK and some typical examples of steady and transient process of simulation results are given.
