Dynamic balancing of mechanisms with flexible links

The dynamic balancing of flexible mechanisms, that is, the reduction or elimination shaking forces and moments on support structure, is considered. Two approaches are pursued: one uses similarity other modal balancing. A single rotating link can be balanced by a properly scaled countermass, for which criteria given. If all conditions satisfied, force balance even achieved if geometric non-linearities taken into account. This extended to translator. Owing unscaled pitch translator asymmetric driving motor, no perfect achieved, but results considered satisfactory. Then, four-bar mechanism with coupler means shown. supported at nodes first free vibration mode, this mode suppressed in moment response. By supporting four points two whippletree contribution three symmetric modes significantly reduced. • Dynamic principles mechanisms links introduced. method mechanism. second link. methods applied rotator,
