    Abstract
  • In order to predict the hysteresis characteristics of finger seal accurately,minimum hysteresis representing hysteresis characteristics of finger seal was proposed.Then minimum hysteresis mathematical calculation method was established,the correction coefficient of model was determined and verified by experiments.The influence rules of the structure and working condition parameters of finger seals on the hysteresis characteristics were studied and obtained based on the modified calculation model.Results showed that the maximum error between the numerical calculation of leakage characteristics considering the hysteresis effect based on modified calculation model and the test results was 7.64%,and the conclusion of model was reliable.The degree of influence of various structural parameters on the hysteresis characteristics of finger seal was in descending order: thickness of each finger laminate,finger repeat angle,arc radius of the finger beam arcs centers,diameter of the finger base circle,width of the interstice between fingers,and arc radius of finger beam.The results provide a theoretical basis and basis for further research on the influence of hysteresis on the finger seal leakage characteristics and the optimal design of finger seal structure.
