Abstract (english): Optimal ship forms for minimum total resistance in shallow water Optimal ship forms for minimum total resistance in shallow water: An attempt is made to obtain shallow-water optimal ship forms for total resistance by means of "tent" function representation under the constraints that the main dimensions of the ship and the water-line area were kept constant. The objective function in the quadratic programming is the sum of wave-making resistance calculated by Sretenski's formula and viscous resistance calculated by "1+k" form factor method. Thus, the present method can be used to obtain arbitrary-deep-water optimal ship forms for total resistance. Under equal geometrical constraints the shallow-water optimal ship form is obviously different from the deep-water optimal ship form. It is feIt that for shallow water the wave resistance is much more sensitive to the bow geometry than for deep water. In the optimization process, it is shown that a practical optimal ship form, of which resistance performance was obviously improved, can be reached under a set of appropriateinequality-constraints.
