Abstract: The paper addresses the design and analysis of a gravity balancer for a marine power plant, aimed at increasing vibro-isolation effectiveness and reducing structural noise. The research is based on the application of zero-stiffness systems in the supports of marine power units. A gravity balancer design based on a multi-disk friction coupling is proposed, ensuring the creation of constant pressure and compensation of the vibration source weight. A balancer’s design algorithm, mathematical model, and new effectiveness evaluation criteria have been developed based on the difference between excitation and inertial forces. The results obtained confirm that the proposed approach is promising in terms of improving vibro-protection systems for marine power plants and reducing vibration levels.

Key words: marine power plant; vibro-isolation, gravity balancer; zero-stiffness system, multi-disk friction coupling; vibro-protection; structural noise; constant pressure system; mathematical modeling; vibration reduction.
