In the flight of a certain aircraft

the maximum deformation of the wing will be up to 3 meters

which will seriously affect the handling performance of the steel cable transmission device installed on the aircraft wing. Considering the cost

difficulty and risk of handling performance in the real flight

a ground wing bending simulation system is constructed. Firstly

a semi-physical simulation model for the whole wing is constructed

which consists of 16 sets of mechanisms. Each mechanism is equipped with a set of displacement servo control system and an angle servo control system. Then

the angle control and displacement control of the wing bending simulation system are modeled and simulated

and an effective control strategy by combining feedforward and fuzzy control is put forward. Finally

an experimental verification system is built to verify the rationality of the simulation system. The results show that this system is reasonable in design and strong in practicability

and can meet the test of steel cable handling performance under wing bending deformation.
