In the alpine environment, the flap movement of civil aircraft is easily affected by frozen ice. At present, there are few experimental data on the adhesion strength of frozen ice that can be used to simulate the ice-breaking load of civil aircraft flaps, and the temperature points do not meet the actual use scenarios. To study the dynamic change law of the flap motion mechanism when breaking ice under the condition of ground icing, this paper conducts icing adhesion strength tests at different icing temperature points that meet the actual use scene, and calculates the icing resistance moment under different working conditions according to the experimental data. The icing resistance moment under the condition is the simulation load input. By changing the icing width of the seam to simulate different icing conditions, the process of ice-breaking motion of the flap moving mechanism is simulated, and the general process method of the ice-breaking motion simulation of the moving parts of the civil aircraft is formed, which calibrates the ice-breaking load values of aircraft moving parts under various icing conditions. The research results show that the combination of measured data and dynamic simulation can obtain the variation law of driving torque in the ice-breaking motion of moving parts under various icing conditions, as well as the critical conditions of aircraft use. In addition, the validity and engineering practicability of the method in the anti-ice movement of the civil machine are verified.
