Complete Shaking Force and Shaking Moment Balancing of Linkages

Abstract

In this Chapter, new methods for the full shaking force and shaking moment balancing of linkages are considered. In Sect. 4.1, a new solution for the full shaking force and shaking moment balancing of four-bar linkages is discussed, which allows the complete shaking force and shaking moment balancing of in-line four-bar linkages with constant input speed by adding a class-two Assur group, i.e. a group which does not add any supplementary degree of freedom into the mechanism. It should be noted that the balancing of the shaking moment without counter-rotations of three particular classes of four-bar linkages is known and it was mentioned in the overview (see Sect. 2.1). However, such a method cannot be extended to general four-bar linkages. In the mentioned Section, it is proposed to dynamically balance the in-line four-bar linkages by adding articulated dyads.
