Abstract: Taking advantage of character of the mechanism motion and introducing interrelation of the change of total mass center to the effects of every factors on total mass certert from generalized optimums a new method for shaking force balance of plane mechanism is presented. The example in the paper fully shows the merits of the method: simplicity, practical and good effect, especially obvious for plane complicated mechanism.
