Torsion experiment device and simulation method of large opening ship with unbalanced cargo loading

Abstract

The invention discloses a torsion experiment device for a large-opening ship unbalanced in cargo loading and a simulation method. The torsion experiment device comprises a ship model, a base, dowel bars, connection rods and supporting columns. The ship model is fixed on the base through first rigid rods at two ends, four loading water tanks are mounted on two sides of the ship model symmetrically through the dowel bars, each two corresponding loading water tanks on two sides are connected through the connection rod, the middle of each connection rod is connected with the corresponding supporting column through a second rigid rod, and the second rigid rods are in hinge joint with the connection rods and the supporting columns. Angular displacement sensors are mounted at torsion axis positions of the ship model, a plurality of strain sensors are arranged on the ship model and are connected with a charge amplifier which is used for amplifying signals, and the amplified signals are collected by a signal collector. The torsion experiment device is manufactured by simulating a large-opening ship torsion principle to serve as an experiment device in teaching and makes experiments real and observation easy by loading torque to simulate ship loading unbalance conditions, thereby being convincing.

Description

technical field [0001] The invention relates to a torsion experiment device and simulation method of a large-opening ship with unbalanced cargo loading, 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, and the large opening ships represented by container ships have greatly improved the loading and unloading efficiency due to the large openings of their cabins, so that their number is increasing. However, due to the structural characteristics of large openings, the torsional strength of ships with large openings is weakened, resulting in more and more accidents, so the research on the torsion of large opening ships is becoming more and more important. [0003] There are two main reasons for the twisting of ships with large openings: [0004] 1. The ship is subjected to torque when sailing in waves; [0005] 2. The ship is subj...

Problems solved by technology

[0005] 2. The ship is subjected to torque due to unbalanced cargo loading;

[0008] (1) The torsional moment suffered by the ship is much smaller than the total longitudinal bending moment, so people do not pay enough attention to the research on the torsional strength of the ship, and the students also lack the understanding of the torsional strength of the ship during the study, but the torsional strength is relatively large for a ship with a large opening. Said that its importance is more worthy of attention than the overall longitudinal strength
