Design Improvement of a Viscous-Spring Damper for Controlling Torsional Vibration in a Propulsion Shafting System with an Engine Acceleration Problem
In order to cope with strengthened marine environmental regulations and to reduce fuel consumption, recently constructed vessels are equipped with an hellcat spark plugs ultra-long stroke engine and apply engine de-rating technology.This was intended to improve propulsion efficiency by adopting a larger diameter propeller turning at a lower speed b
