This book was released on 1971 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method is developed for predicting propeller-generated hull surface forces which cause a ship to vibrate. The method applies specifically for vertical, athwartship, axial, or torsional steady-state vibration of the hull girder. The exciting forces are made available as generalized forces effective in exciting the normal modes of the hull free vibration. The free vibration characteristics are assumed to be known in advance. The formula by which the generalized forces can be calculated is derived using potential flow theory. The basic ingredient in the derivation is a theorem which permits the problem to be solved without need for the solution of a hull-propeller interaction boundary value problem. To use the method one must have available: data pertaining to the hull and propeller design, the hull normal mode shapes, an estimate of the propeller blade loading distribution, and the fluid velocity-potential function corresponding to free vibration of the bare hull in each normal mode. Very simple, yet accurate, strip formulas for estimating fluid velocity-potential function, the bare hull velocity potential, and associated velocity components, are derived for the case of hull vertical vibration.

This book was released on 1982 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: An existing technique for determining free space pressures generated by a cavitating propeller operating in a ship wake is used as the basic input for determining the pressure distribution on various ship sections. The procedure involves establishing a boundary value problem on the ship section and the free surface, with appropriate conformal mapping operations that allow conversion of the problem to a more simplified boundary, viz. a flat plate and its adjacent free surface which represents the boundary for the lower half-plane. The integral equation for solution of this problem to determine the pressure is established and solved analytically, with evaluation carried out by means of digital computation in terms of the various physical parameters and those obtained from the mapping procedure. The solution provides the pressure distribution at different sections on the hull, from which the total forces are then determined via integration with this strip theory approach. In addition the effects of different mode shapes of hull vibration are incorporated in order to obtain generalized forces for determining hull vibration responses.
