A multi-layered lamina emergent mechanism configuration was designed, combined with classification scheme and rigid body replacement synthesis design approach. Based on pseudo-rigid-body model and analogous linear coil spring model of lamina emergent torsional (LET) joint, the force deflection relationship was derived. With the aid of finite element analysis, the results of the two methods were compared and the causes of error were analyzed. The results obtained by the two methods were approximated. This indicated that the analysis and design methods were correct and feasible.
