Анализ развития крутильных колебаний в судовых валопроводах при использовании маховиков-демпферов

The application of a damper does not efficiently reduce stress from torsional vibrations in 60 % of considered machine-propulsion complexes with eight cylinder diesel engines at direct power transmission on the screw propeller. As a result, prohibited areas have been marked within the operation of rotational speed of crankshafts of main diesels. The construction of a flywheel-damper was designed on the basis of construction characteristics of torsional vibrations of silicone dampers. Design-theoretical analysis of the development of torsional vibrations with the flywheel-damper mounted in different positions on the propeller shaft has shown the following: the application of the flywheel-damper results in an effective reduction of torsional vibrations and in ifying the prohibited areas within the operation of rotational speed of the machine-propulsion complex with eight cylinder diesel engines. The best result is achieved by mounting the flywheel-damper in the place of a damper.
