Abstract

The invention relates to a small waterplane double-hull wave load test model design and test method. Models which are consistent with the weight distribution, geometric similarity and motion similarity of all sections of a real ship are manufactured, the models are subjected to segmentation processing, a measuring beam frame is arranged, and through load collection and analysis calculation of strain gauges on the measuring beam frame, ship motion state parameters and main loads borne by the ship body are accurately obtained. The method can be used for measuring data of six-degree-of-freedom motion and acceleration of a small waterplane catamaran model in waves and for measuring seven key wave load values such as vertical wave bending moment and shearing force, vertical shearing force of amiddle longitudinal section, transverse opposite opening force and transverse wave bending moment, horizontal torque and overall asynchronous pitching torque. The method has very important significance in mastering wave load characteristics of the type of ship and determining reasonable structural design loads.

Description

technical field [0001] The invention relates to the field of ship structure design, in particular to a design and test method for a small waterplane area double-hull wave load test model. Background technique [0002] Wave load is the most important load to be considered in ship structure design, and the correct selection of wave load is an important basis for optimizing ship structure design and reasonably evaluating ship strength. Accurate assessment and adoption of reasonable design loads are the basic elements of structural design. [0003] The appearance of the small waterplane area catamaran is very different from that of the monohull. It is a П-type composed of the main hull, pillars, submerged body and connecting bridge. Its unique geometry also determines its structural load characteristics to be different from those of a monohull. The external wave loads of small waterplane area catamarans include vertical wave bending moment and shear force, transverse split for...
