ACTIVE MEASURES AGAINST HULL VIBRATIONS IN A 10,400-TONNE CARGO SHIP
After its propeller had been changed, this East German cargo-ship, with a main engine of 4,300 kW at 130 rpm, exhibited horizontal vibration that affected crew comfort in the accommodation and working areas to an unpleasant extent. The Authors describe and discuss the measurements and calculations that were made to determine the causes of this hull vibration and enable a compensating weight to be fitted to the shafting as an antiexcitation device for first-order vibrations. Practical experience and experimental results from the adjustment of the mass and angular position of the compensating weight are also described, and it is shown that it is relatively simple to eliminate this type of hull vibration in this way.
