Development of a Model Spring Torsional Vibrations Damper

Abstract

Spring torsional vibration dampers with hydraulic fillers in the form of motor oil recently became quite widespread in the main power plants of ships. Such leading manufacturers as Wartsila (Finland), MAK (Germany), Caterpillar (Japan) and others, began to install spring torsional vibration dampers in the marine diesel engines along with the traditional silicone dampers. This is caused by complicated design schemes of the ship propulsion systems, installation of the high rotation velocity supercharged diesel engines, introduction of steering columns, elastic couplings, cardan shafts and other elements, which increases the number of dangerous resonant torsional vibrations and makes the use of spring dampers more efficient, unlike the silicone ones. Though theoretical basis for calculating parameters of the spring torsional vibration dampers is provided in a number of sources, results of practical research by the foreign manufacturing companies remains mostly as the classified information. The paper describes a method for design and development of a model spring damper. Research could be conducted in laboratory conditions at the stand of the MTS Testing Center of the FSBEI HE "ASTU" to study the dampers performance depending on their technical condition, as well as other topical issues in the torsional vibrations area
