Compliant Mechanism Design of Multiphase Material Wing Leading Edge

This article introduces a method of the compliant wing leading edge with multiphase materials. The alternating active phase algorithm is used to establish the optimization model of multiphase material compliant mechanism. The least square error (LSE) between the deformed displacement and target displacement of the control points is defined as the objective function. The MATLAB codes are developed to solve the optimization problem. By the MATLAB, a distinct topology image of wing leading edge with two sold materials is obtained. In addition, the CATIA software is used to smooth and reconstruct the results. Finally, the reconstructed model is imported into the HyperWorks software for simulation analysis. The result shows that the multiphase compliant wing mechanism can achieve the maximum deflection of 9.27 °under actuator force.
