Abstract: In this paper, a method calculating shaking force of elastic linkages is presented. An example given in this paper reveals that it may be harmful to use traditional methods to balance an elastic linkage. By optimizing the masses attached at the ends of the links, the shaking force can be minimized. On the bases of optimality criterion technique, a new approach is developed in which the maximum shaking force produced during the complete cycle of motion of the linkage is minimized through modifying cross-sectional parameters of the links.
