Application of Torsional Dampers for the Vibrations Reduction in Crankshafts of Piston Aircraft Engines [PDF]
MATEC Web of Conferences, 2022 It is a well-known fact that piston engines shake, among which some of them more than others. Therefore, such type of vibrations, created by piston engines, should be controlled somehow.

Method for Adjusting Torsional Natural Frequencies of Powertrains with Novel Coupling Design
Machines, 2022 Torsional vibrations are inherently present in every rotating powertrain. In resonant conditions, torsional vibrations can be significantly amplified. A typical method to reduce the torsional vibration particularly at resonance is to modify the torsional
