The invention belongs to the technical field of hull structure strength experiments, in particular to a slat beam bending moment experiment device with uniform sensors. The invention can truly simulate the multi-layer deck structure of the ship hull, and at the same time, the force change of each layer of slat beams when the structure is plastically damaged can be obtained approximately. The present invention adopts several slat beams instead of plate structure as the structure of each layer, which can weaken the strength of the whole structure, and ensures that the model can be easily plastically damaged on the basis of satisfying the dimensional characteristic requirements of the model. The invention simulates the axial tension and pressure of each layer of the structure of the ship's section through the tension and pressure sensors evenly distributed between the two layers of plywood, and can obtain the force of each layer of the position of the section to be measured by conversion; The mechanical sensor that comes with the equipment measures the vertical pressure, and the bending moment at the position of the section to be measured can be obtained by conversion.
Description
technical field [0001] The invention belongs to the technical field of hull structure strength experiments, in particular to a slat-beam bending moment experiment device with uniformly distributed sensors. Background technique [0002] When studying the hull strength, the ultimate strength of the hull girder structure is closely related to the overall longitudinal strength of the ship, which is an important factor to ensure the safety of the ship. From the perspective of the safety of the ship, the bearing capacity of the hull girder structure should not only pay attention to the ultimate strength of the structure, but also It is also necessary to pay attention to the post-ultimate strength behavior after collapse in sudden extreme sea conditions, and to be able to predict the final bearing capacity and damage degree after collapse based on the structural state of the hull girder and external loads. On the transverse section of the ship, the damage of the ship under the acti...
