The invention belongs to the field of airborne equipment testing, and relates to an aircraft wheel deceleration simulation method. The method comprises the steps that S1, when an airplane wheel is located on the ground, the braking torque is determined according to a braking instruction, the wheel speed and the temperature of a brake disc; s2, energy generated by braking is calculated based on the braking torque and the airplane wheel angular speed, and meanwhile environment loss energy caused by heat dissipation is calculated based on a preset energy loss function; s3, the total braking energy is calculated based on the energy generated by braking and the environment loss energy; s4, the brake disc temperature under the total brake energy is calculated based on a preset brake disc temperature function; and S5, substituting the temperature of the brake disc into the step S1, recalculating the brake torque, and cyclically executing the steps to realize airplane wheel deceleration simulation. The dynamic characteristics of the tire pressure, the brake torque and the brake temperature in the braking process of the airplane are simulated.
