Vibrations of Marine Propulsion Diesel Engines

Vibracije motora i njegovih dijelova mogu izazvati: momenti prevrtanja motora; sile i momenti uzrokovani inercijom rotirajućih masa; sile i momenti uzrokovani masama i oscilatornim (reciproaktivnim) gibanjem; nejednoliki zakretni moment motora. Ako se pravilno razmotre aspekti vibracija u ranoj fazi, dostupne protumjere pružaju dobru sigurnosnu marginu protiv potencijalnih problema s vibracijama. Vibracije motora mogu se ukloniti, odnosno ublažiti prikladnim razmještajem cilindara, upotrebom protuutega itd, u protivnom ih moraju preuzeti konstrukcija motora, postolje i spojevi.Vibrations of the engine and its parts can cause: engine overturning moments; forces and moments caused by the inertia of rotating masses; forces and moments caused by masses and oscillatory (reciproactive) motion; uneven engine torque. If aspects of early-stage vibration are properly considered, the available countermeasures provide a good safety margin against potential vibration problems. The vibrations of the engine can be removed or mitigated by a suitable arrangement of the cylinders, the use of a counterweight, etc., otherwise they must be taken over by the engine structure, base and joints
