In this paper, we present an effective method for designing the compliant mechanisms by the topology optimization technique using the homogenization design method. In this method, a new multi-objective function which maximizes the relative compliance between input at the loading point and output at a prescribed point is defined. The topology optimization problem formulated using the homogenization design method is solved by SLP method. In this algorithm, with the size of the hole of unit cell, the angle of unit cell is made to be a design variable. The local minima occurring in topology optimization in which SLP method is used and the gray scale densities of optimal solutions are improved by .our presented methods. The effectiveness of the present method is demonstrated by numerical examples of the topology optimization on a short cantilever plate.
