In this paper, a topology optimization method of elastic link mechanisms is shown. In these mechanisms, the displacement of the output point can be controlled by the load of the input point. The mechanism obtained by the present method is composed of the frame structure with elastic members and semi-rigid connections. The ground structure approach is used in order to obtain the optimum topology of the mechanism. In the optimization problem, both of the sectional area of the members and the rigidity of the connections are chosen as design variables. The stiffness between the input point and the output point is maximized under the total weight constraint and the displacement constraint of the output point. The optimization problem is solved using the SLP optimizer. Several examples are shown to demonstrate the effectiveness of the present method.
