Abstract

in the ship propulsion systems the engine - torque is through high-flexible coupling on the main gear transmitted. The high flexibility of the coupling is demanded because of the required correct collaboration of the flexibly supported engine and the main gear. Such a system is characterized by its considerable sensitivity to the periodic, harmonic or random disturbances. Particularly dangerous are the signals created by the irregularity of engine running In this case exists the possibility of appearance of the propulsion system resonance with some harmonic components of the periodic (or random) disturbances. From the exploitation experience are known the emergencies of considerable torque overshoot of the coup
