推导出了超-超引射器性能计算和优化设计模型,借助Pareto优胜、Pareto最优解和Pareto前端等概念,采用基于多目标进化/分解算法(MOEA/D)的多目标优化方法,计算得到超-超引射器多目标优化问题的Pareto前端,解决了超-超引射器多目标优化设计问题,并与常规参数分析方法进行了比较。结果表明:超-超引射器性能影响参数相互关系复杂,增压比和引射系数作为引射器主要性能参数相互冲突,通过常规分析难以得到较清晰的设计准则,利用多目标优化设计方法可有效地辅助多属性决策和系统优化设计。
Based on the concepts of Pareto winning, Pareto optimal solution and Pareto front-end, the multi-objective optimization method based on multi-objective evolution / decomposition algorithm (MOEA / D) is used to calculate and optimize the performance of the super- The Pareto front end of the multi-objective optimization problem of the super-ejector is obtained, which solves the multi-objective optimization design problem of the super-ejector and compares it with the conventional parametric analysis method. The results show that the relationship between performance parameters of super-ejector is complex, and the supercharging ratio and ejector coefficient conflict with each other as the main performance parameters of ejector. It is difficult to get a clear design criterion by routine analysis. By using the multi-objective optimization design method Can effectively assist multi-attribute decision-making and system optimization design.
