Modeling and Simulation of Wing Bending Simulation System
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.
