摘要/Abstract

摘要： 应用GT-Power和Simulink软件建立了发动机瞬态过程仿真平台,并应用此平台对发动机瞬变过程进行模拟分析,提出了改善发动机瞬态性能的增压器改进方案。通过试验对模拟计算结果进行了验证,发动机定转速增转矩的瞬变过程所用的时间缩短31%,整车起步换挡加速到60 km/h所用的时间缩短了8.7%。试验结果与模拟计算结果在趋势上吻合较好,验证了用模拟计算方法进行发动机瞬态性能预测的可行性。应用这种模拟分析方法,可以在性能设计初期对发动机和整车的瞬态性能进行分析评价,指导发动机增压器匹配方案选择。

Abstract: A co-simulation platform was built using softwares GT-Power and Simulink to analyze the engine transient performance. The platform was used to simulate the transient process of a turbocharged engine, and a modified turbocharger variant was put forward to improve the transient performance of the engine. The simulated results were verified by engine tests, showing that the time for the load step of constant speed and increasing torque was reduced by 31%, and the vehicle accelerating time from 0 to 60 km/h was reduced by 8.7%. The test result trend was in good agreement with that of simulation, proving the feasibility of predicting the engine transient performance by simulation. The proposed simulation method may be used to analyze and evaluate the transient performances of the engine and the whole vehicle at the early stage of engine performance development, guide the matching of the turbocharger with the engine.

Key words: power machinery and engineering, engine, turbocharger matching, transient performance simulation, GT-Power
