An optimization technique for the balancing of spatial mechanisms

This paper presents a new generic optimization technique for the balancing of the shaking force and shaking moment due to inertia forces in spatial mechanisms. For given dimensions and input speed of a mechanism, the inertia forces depend only upon the mass distribution of the moving links. The equimomental system of seven point-masses is introduced to represent the inertial properties of the links and to identify optimizing variables. The effectiveness of the proposed methodology is illustrated using a spatial RSSR mechanism.
