The invention discloses a model parameter equivalent correction method for aircraft tire rigidity testing, and relates to the technical field of aircraft testing, and the method comprises the following steps: S1, test system construction; s2, carrying out a test experiment; and S3, data fitting. According to the invention, the rigidity test of the aircraft tire under the influence of various motion states can be realized, and the equivalent aircraft tire rotating speed and equivalent vibration frequency which can be completed under the laboratory condition can be obtained according to the real rotating speed and vibration frequency of the aircraft tire equivalently, and are finally imported into a shimmy analysis model. The precision of undercarriage shimmy analysis can be improved, and the precision of aircraft taxiing stability analysis can be improved.
