To increase the accuracy as well the production speed of industrial machines, dynamic balance is becoming a key issue. Instead of applying complicated control strategies to reduce machine vibrations, and damping systems to suppress vibrations, in dynamic balancing the mechanism parts are considered and designed such that the machine does not vibrate at all. Surprisingly however, dynamic balancing techniques are not yet widely applied. This is probably due to the lack of knowledge of dynamic balancing and the fact that in general relatively a lot of mass and inertia is added to obtain a dynamically balanced mechanism. This study focuses on the reduction of the additional mass and the additional inertia with dynamic balancing. For that purpose common balancing principles are analyzed and compared, guidelines for low mass and low inertia dynamic balancing are formulated, and new balanced mechanisms that have a low mass and low inertia are synthesized.
