Problems solved by technology

[0003] At present, the discussion of the shear force in the calculation of the longitudinal strength of the ship is mainly focused on the calculation and software analysis. In the teaching, only the external force of the shear of the ship can be discussed, and the students cannot intuitively see the shear of the ship. Shear failure, thus affecting students' understanding of the damage caused by the shear force on the ship

Abstract

The invention discloses an experiment device of a shearing stress exerted on a goods loading imbalance boat. The experiment device comprises a water tank, a sectional boat model is placed in the watertank, the sectional boat model comprises several boat model units, a center shaft rod is arranged in the geometric center of each boat model unit and penetrates through the boat model unit, one end of each center shaft rod is fixed to the bottom of the water tank, bearing sleeves are arranged on the boat model units and sleeve the center shaft rods, the adjacent boat model units are connected through a vertical slide rail and are locked through a plug pin, the plug pins are controlled through electromagnetic relays, and an annular buckle is arranged on each boat model unit and is connected with the corresponding center shaft rod through a spring. By means of the experiment device of the shearing stress exerted on the goods loading imbalance boat, the shearing stress exerted on the boat isdisplayed through instrument equipment, deformation damage occurring after the shearing stress is exerted on the boat is observed, and a student conveniently grasps knowledge in the aspect of the boat shearing stress.

Description

technical field [0001] The invention relates to an experimental device for shear stress on a ship with unbalanced cargo loading, belonging to the field of teaching experimental instruments. Background technique [0002] In the calculation of the overall longitudinal strength of the hull, the ship is usually placed on the water surface, and the shear force, bending moment and corresponding stress on the hull girder cross section are calculated, and compared with the allowable stress to judge the hull strength. Because the bending moment load is convenient to load, easy to control and operate, in the previous experimental research, the bending moment was often simply discussed, and the influence of ship shear force on the longitudinal strength of the ship was ignored. Even if shear is involved in the discussion, only the relationship between shear and bending moment is mentioned. [0003] At present, the discussion of the shear force in the calculation of the longitudinal str...
