摘要
通过对各部件特性的研究,提出一种简化部件计算过程的方法,该方法的最大特点是在某些部件的计算中使用很多通过试车数据所发掘的经验公式,用以代替那些繁琐的热力学计算,并合理选取初猜值,使模型能更快收敛,从而减少运算时间,提高模型的实时性。通过对比常规建模方法所建模型,可看出该模型具有实时性、稳定性好的优点。
A method of simplifying the process of calculating of the components is put forward via the study of all kinds of the components' characters in the paper. Lots of experiential formulas are used in the process of calculating of the components instead of the complicated energetic computing, which is the most notable feature. And the proper initial guess values are chosen, which makes the mode converge quickly. So the time of computing is reduced and the real - timing of the mode is improved. The mode with high real - timing and stability is showed through the contrast of the common method.
