Structural Design and Experiment Analysis of a Morphing Wing Structure
Abstract
A morphing wing structure is proposed by using planar multi-closed loop linkage. The mathematical model of the structure is established. The mechanism trajectory is simulated and analyzed in Matlab by using the structural mathematical model. In order to verify the curvature adjustment ability and aerodynamic characteristics of the mechanism， a three-dimensional model of the mechanism is established， and the kinematics simulation and aerodynamics simulation analysis are carried out. In order to obtain better aerodynamic characteristics， an improved artificial fish swarm optimization algorithm is proposed based on the traditional artificial fish swarm optimization algorithm. The performance of the algorithm is tested by the classical optimization algorithm test functions. The optimization algorithm is used to optimize the morphing wing structure. On the basis of theoretical research， the experimental prototype is processed and the related experimental tests are carried out.
