指尖密封性能的模糊Nash平衡优化

针对工程应用中对指尖密封泄漏率和磨损率具有不同偏好要求的情况,通过集成Nash平衡博弈理论和模糊综合评判理论,建立了满足不同偏好要求的指尖密封性能模糊Nash平衡优化模型,研究了若干偏好要求条件下的指尖密封性能多目标优化问题.研究结果表明,与现有研究方法相比,提出的计算方法不仅有效地反映了工程中对各优化目标的不同偏好要求,而且大大减小了指尖密封性能多目标优化的决策工作量,提高了优化效率,其优化结果也较为理想.

Performance optimization for finger seal based on fuzzy Nash equilibrium game

For the purpose of multi-objective optimization of finger seal with different preference requirements in engineering application,the fuzzy comprehensive evaluation was introduced into Nash equilibrium game,and performance optimization model with uncertain payoff of finger seal was built.By using the presented model,the performance multi-objective optimization problems with uncertain preference requirement for finger seal were researched.As compared with exiting methods,the results show that the presented method can not only effectively reflect the different response requirements of optimization objectives,but also significantly reduce the decision-making difficulty of multi-objective optimization for finger seal performances.Furthermore,the finger seal structure obtained through presented multi-objective method has good performances.
