Abstract

The invention discloses a ship torsion principle simulation device and method. The simulation device comprises a sink, a ship model, a sensor system, a signal conditioning and sampling system and a terminal, wherein the ship model is provided with a big opening; the terminal is provided with a display unit; the ship model is connected with sink walls at the two ends of the sink by an axle longitudinally penetrating through the torsion center of the ship model; the ship model can carry out torsion with the axle as the center; a plurality of baffles are arranged in the space from the ship model to the sink walls and the sink bottom surface; one ends of the baffles are fixed on the sink and the other ends are connected with the ship model by flexible films; and the space is divided into a plurality of unit watertight cavities surrounding the ship model by the baffles and the flexible films. The simulation device can be used for vividly and intuitively demonstrating and verifying the harms of torsion to big-opening ships to attract attentions of students to torsion of the big-opening ships, so that the students more intuitively know the knowledge that the ships are subjected to torsion in waves, thus effectively improving the teaching effects.

Description

technical field

[0001] The invention relates to a simulation device and a simulation method of a ship torsion principle simulation device, belonging to the field of teaching experiment instruments. Background technique

[0002] With the development of global economic integration, the ocean transportation industry is developing rapidly. Large-opening ships represented by container ships are widely used because the large openings of their cabins can effectively improve the loading and unloading efficiency. Compared with the total longitudinal bending moment, the torsional moment experienced by ordinary ships sailing on the water is much smaller, so people have not paid enough attention to the research on the torsional strength of ships, and students also lack the understanding of torsional strength of ships during their studies. The structural characteristics of its large opening lead to the weakening of the torsional strength of the hull, which has also caused many accidents....
