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. Aiming at the different preferences of fingertip seal leak rate and wear rate in engineering application, a fuzzy Nash equilibrium optimization model of fingertip sealing performance satisfying different preferences is established by integrating Nash equilibrium game theory and fuzzy comprehensive evaluation theory. The results show that compared with the existing research methods, the proposed calculation method not only effectively reflects the different preferences of the optimization objectives in the project, but also significantly Which reduces the decision-making workload of multi-objective optimization of fingertip sealing performance and improves the optimization efficiency, and the optimization result is also ideal.
