Abstract:

By introducing a set of tent functions to approximate the ship hull function, the Michell integral for wave resistance is reduced to a standard quadratic form in terms of ship offsets. With linear-inequality constraints of the type 0 less than or equal to Hx,z less than or equal to B C less than or equal to Hxx,z less than or equal to D, Hx,z is hull function B, C, D are constants, it is possible to find various optimal ship forms of minimum wave resistance by applying quadratic programming techniques to the problem. Three optimal forms have been chosen among a number of computed results for tests in the ship-model towing tank. Author
