Abstract: The current work obtained the seal rotor displacement excitation through studying
the association rules of rotor speed, rotor unbalanced force and rotor runout based on dynamic
working characteristics of finger seal. Then, a dynamic computational model of finger seal system
was constructed. The leakage clearance computation method was researched according to the
dynamic displacement response characteristics from the constructed model. Then the dynamic
leakage calculation method was constructed and the leakage analysis work was conducted. The
results preliminarily shows that dynamic displacement response changes with the rotor
excitation time in every rotation period. The dynamic leakage clearance produced by dynamic
displacement response also changes with the rotor excitation time. The results also indicate that
leakage numerical size is affected by working conditions, installation conditions and the abrasion
