Abstract: Vibration, generated by the ship's diesel generators, is one of the primary sources of structural noise, which negatively affects the living and working conditions of the crew. Traditional sound insulation systems are characterized by limited efficiency due to resonance phenomena across a wide frequency range, dependence on stiffness, and sensitivity to changes in operating conditions. The research presents a methodology for weight compensation in the support of a ship’s diesel generators, based on the concept of zero stiffness and implemented using a multi-disk dry friction compensator. A dynamic mathematical model of the system has been developed, and numerical simulations have been performed. The results obtained confirm that the compensation provides force balance and slightly reduces the dynamic reaction, transmitted to the base.

Key words: diesel generator, ship vibration, vibration isolation, zero stiffness system, dry friction compensator.
