PROPELLER-EXCITED VIBRATION WITH PARTICULAR REFERENCE TO FULL-SCALE MEASUREMENTS

The paper presents work for a comprehensive set of full- scale measurements of ship vibration responses. Service data have been presented in terms of blade passage frequency and its harmonics. For the former a summary of data from 25 trials has been given in the form of a presentation of the mean vertical vibration at the stern gland against a power-geometry factor. In addition, data are given which relate the mean vibration levels at a standard measuring position at the wheelhouse top to the stern gland responses. It is suggested that such information can be used as a basis for comparison and prediction of mean vibration levels for new ship designs. The responses for the higher harmonics have been presented in a way which helps to define those characteristics which are associated with the more severe cases of propeller-excited vibration.
