TRANSVERSE VIBRATIONS OF SHIP'S PROPULSION SYSTEMS. PART 2 EXPERIMENTAL ANALYSIS

Due to increasing ship dimensions and installed propulsive powers, resonance frequences of the propeller-shaft system tend to decrease. Regarding transverse vibrations one has nowadays to be aware of the fact that resonance frequencies may be within the operating range of the shaft rpm. Therefore a calculation method was designed to have a fairly accurate estimate of the resonance frequencies in the design state. This method, presented in part I of this report, was applied to the shafting of the third-generation containerships owned by the Netherlands Shipping Union. To verify the results of the calculation, impact excitation measurements were carried out on the non rotating shaft with ship in dry dock and with ship afloat. Measurements were also performed with ship in operating condition. This report presents the used methods and the results. The results of the calculation and those of the measurements show a corresponding picture.
