DescriptionMechanism design consists of two parts: kinematic synthesis and kinematic analysis. The classical kinematic analysis based on graphical method or analytical method is hard to implement into computer program and have accuracy issue. In this work, a novel analysis method called the Constrained Superposition Method (CSM) is presented base on Finite Element Method (FEM). The new method is based on the penalty formulation on constrained boundaries in the finite element analysis and then applies superposition to two constrained systems for linkage analysis. Genetic Algorithm (GA) is combined with this new analysis method to solve mechanism synthesis problem. To further improve the efficiency of evolutionary optimization process, two feasibility checks are introduced to ensure the connectivity and mobility. Design examples generated from this approach will be presented.
