The starting of the system by harmonic excitation is considered on the assumption of uniformly varying frequency and constant amplitude of the forced moment. Simultaneous structural friction phenomena (passive damping) and piezoelectric effect (active damping) have been considered as well. The problem is considered on the assumption of a uniform unit pressure distribution between the contacting surfaces of friction discs and plunger. The aim of the analysis is to asses the influence of angular acceleration, unitary pressure, external load and electric parameters on the resonance curves of the starting vibrations. The equations of motion of the tested system were solved by means of the Krylov-Bogolubov-Mitropolski method and digital simulation method.}, type={Article}, title={Damping of vibrations through torsion damper during starting power transmission system}, URL={http://journals.pan.pl/Content/124995/PDF-MASTER/4_MECHANICAL_51_2004_2_Skup_Damping.pdf}, keywords={torsion damper, structural friction, passive and active damping, piezoelectric effect, actuator, sensor}, }
