Multi-objective Hybrid Teaching-learning-based Optimization Method for Structural Parameters of Finger Seal Open
摘要： 作为一种先进柔性密封,指尖密封结构参数对其性能的影响较为复杂,传统建模方法难以有效刻画两者间的映射关系,这导致指尖密封结构参数的优化难以实现。为此,首先利用BP神经网络构建迟滞率、平均接触压力和基圆半径、指尖梁个数等多个结构参数间的拟合关系,并在此基础上建立同时最小化迟滞率和平均接触压力(Minimize hysteresis-rate and average contact pressure,MHACP)的多目标优化问题模型;然后,设计结合Pareto支配法的混合…
