    Abstract
  • Considering the present unsolved problem of improving hysteresis and wear in multi-objective optimization of finger seal,Stackelberg theory is introduced to construct finger seal mathematical model with hysteresis and wear characteristics by treating curve as elements to be optimized.With the lead-follow Stackelberg game mechanism,the controllable optimization of finger seal characteristics is performed based on genetic algorithm combined with backward propagation(BP) network and finite element analysis(FEA) methods.Then the finger seal of up-concave curve with low hysteresis and wear characteristics is obtained.Finally,the FEAsimulation reasonably explains to reason that this type of finger seal has the better characteristics and also show its future in engineering field.
