ESDU 92016 describes a range of established techniques for reducing the torque fluctuation in shafts that drive@ or are driven by@ planar linkages. The fluctuations result from inertial and gravitational effects of the moving links or from variable external loads. The peak-to-peak torque fluctuation may be reduced by appropriate techniques@ of which six are considered. The design considerations involved in the selection are discussed@ and the principle underlying each technique is explained. General design guidance is given for each technique together with a table of typical characteristics so that the designer can assess rapidly the potential of each method for a particular application. The techniques covered include mass reduction of the links@ dyad addition@ addition of springs and dampers@ use of a torsional-vibration isolator and use of a flywheel (which does not reduce peak-to-peak torque fluctuation but@ by increasing the inertia of the shaft@ reduces the effect of the torque fluctuations on the angular velocity). A considerable bibliography lists references giving further information on each method.
