A PILOT STUDY OF TORSIONAL VIBRATIONS CAUSED BY PERTURBATION ACTION OF THE ENGINE’S TORQUE

Authors: M. Tevzadze, Z. Chkhartishvili


Abstract:

For the purpose of identifying all possible resonances in the vehicle's transmission, selecting a more dangerous resonance and the optimal installation of an elastic-friction damper at this resonance, the paper describes the method of a pilot study of torsional vibrations. The paper also proposes the method of installing a damper at resonance, which allows for determining its optimal parameters depending on load condition of engine. As a result of a pilot study of resonance triggered from the engine, the paper presents the elastic-hysteretic characteristics of a damper, which allow for damping the three-phase resonance to be absorbed in the transmission of vehicle under study.

Keywords: Experiment; resonance; damper; vibration
