STRUCTURAL SYNTHESIS OF FRAME REINFORCED SUBMERSIBLE, CIRCULAR CYLINDRICAL HULLS

The report describes an automated computer synthesis capability for the preliminary design of circular, cylindrical "T" frame, stiffened hulls subject to hydrostatic pressure. Given the following hull design parameters: operating depth, bulkhead spacing, mean plating radius, plating and frame material properties (such as allowable stress, Young's modulus, Poisson's ratio, and density), maximum hull eccentricity, the program will automatically generate those values of: plating thickness, frame web thickness and height, frame flange thickness and width, and frame spacing which minimize the hull weight/weight displaced ratio of the hull segment between bulkheads. Design equations or rules control; general instability of the hull, local plating instability between frames, general frame instability, web and flange cribbing, plating and frame yield using factors of safety designated by the designer. The designer can require that the frame diameter not exceed specified limits and can specify limits on the range of permissible values for the plating thickness and frame dimensions.
