Technology Selection and Parameter Decision model for Hybrid Engine
本文中建立了一个在热效率、爆震因子以及排放多指标约束条件下,以费效比最低为优化目标的综合决策模型,其可以快速地为混合动力发动机决策出一系列既可能满足约束条件,同时费效比又偏低的技术及参数组合方案。此模型利用DOE和NSGA-Ⅱ遗传优化算法,可以快速决策出最优的技术方案及其参数。研究表明,利用该模型进行优化计算,相比调用GT-Power求解器计算,同样2000次优化计算的总用时可以从3天缩短至3分钟,大大减少运算时间,且模型的准确度较好,热效率的预…查看全部>>
This paper aims to develop a comprehensive Decision model under the constraint conditions of thermal efficiency, knock factor and emissions, with the lowest cost-effectiveness ratio as the optimization objective. It can quickly decide a series of technical and parameter combination schemes that may meet the constraint conditions and have low cost-effectiveness ratio. This model utilizes DOE and NSGA - II genetic optimization algorithms to quickly determine t…查看全部>>
