Type synthesis to design variable camber mechanisms

This article proposes multiple hinges’ type spectrum that provides an effective description of the multiple hinges of planar kinematic chains. The relationships between characteristic invariants are established and applied into type synthesis methods. A type synthesis method for planar kinematic chains, which is called the characteristic spectrum analysis type synthesis method, is proposed. A systematic design method for variable camber mechanisms is proposed. Using the results of the type synthesis and the systematic design method, three design schemes are proposed and the mathematic models are set up. Some simulation analysis has been done. All these analyses can verify the deformation performance of the proposed mechanism.
