Aviation pipeline flaring joint leakage rate calculation method and system considering contact deformation

The invention discloses an aviation pipeline flaring joint leakage rate calculation method and system considering contact deformation. The method comprises the following steps: based on a Hertz contact theory, converting a guide pipe surface wave crest into a guide pipe surface hemispheroid, converting a pipe joint surface wave crest into a pipe joint surface hemispheroid, and according to the radius of the guide pipe surface hemispheroid, the radius of the pipe joint surface hemispheroid, guide pipe parameters, pipe joint parameters and axial pre-tightening force, calculating a contact threshold value based on a seepage theory and an effective medium theory, and calculating the leakage rate of the aviation pipeline flaring joint according to the contact threshold value. By adopting the method and the system, the problems that the leakage state of the oil tightness test is difficult to quantitatively characterize and the judgment precision is relatively low after the aircraft hydraulic pipeline component-leve
