Based on Ansys FEM method

the Influences of the axial dimensional disposition of sealing pieces in the axial arrangement

under the conditions of different pressure differentials

on the hysteresis and contact pressure of finger seal mechanism have been studied in the current work.A sandwichlike axial arrangement form which has relatively advantageous matching relationship between hysteresis and contact pressure has been shown.The research work here shows that the axial arrangement has quite consideralle influence upon the performance and service life of finger seal mechanism

and therefore the optimization of axial arrangement should be taken into consideration in the optimized design of finger seal construction.
