Dynamic stresses acting on a link depend upon the area of the section of a link and the forces acting on the section, and the inertia forces and the inertia torque depend upon the distributions of masses of a link and the shape of a link. Therefore, it is important for improving the distribution of the stresses of links to design the shape of section of a link for reducing the weight, the shaking force and the shaking moment of the mechanism. This paper presents a design method of the uniform strength links in a planar four-bar link mechanism. The design examples are also given. Both the numerical calculating results and the experimental results show that the method is efficient for reducing the weight of the mechanism.
