Topology Optimization Design of Shape Changing Compliant Mechanism for Wing Trailing Edge

In order to implement the shape adaptive change and structural light weight of compliant wing,this article introduces the compliant mechanism into the trailing edge shape change structural design of wing.A compliant mechanism continuum topology optimization model is presented,which is based on the SIMP(solid isotropic material with penalization) model and takes the displacement deviation between actual and target as the objective function,and the material amount as restriction.The optimized design of the compliant mechanism is carried out by using Matlab programming,and the optimized results under different parameters are discussed,and finally the simulation analysis of the mechanism is done.The result shows that the compliant mechanism can achieve the anticipated shape change,and it proves the validity of the method and provides a methodology fundation for the adaptive wing technology.
