In this paper, the topology optimization method of link mechanisms is shown. In the link mechanisms composed of rigid bodies and hinges, the displacement of the output point can be controlled by the load of the input point. In the present method, the ground structure composed of beams is used in order to obtain the optimum topology of the link mechanisms. In the optimization problem, the sectional areas of the beams are chosen as design variables. The stiffness between the input point and the output point is maximized under the constraints of the displacement of the output point, the relativity displacement of the output point and input point, and the material usage. The optimization problem with different initial design variables are solved using the SLP optimizer, because the solution of this problem depends on the initial design variables. The initial design variables are given by random numbers or GA. Some examples are shown to demonstrate the effectiveness of the present method.
