Shafting experimental device for colliding ship and its collision experimental method

Abstract

The invention provides a shafting experimental device for collided ships. A tail shaft is suspended at a lower part of a collision tank after passing through a tail bearing; a motor is connected to the left end of the tail shaft; a front bearing bracket and a rear bearing bracket are connected to the tail bearing and a transition shaft in the collision tank; and the transition shaft is connected to a deformation rod through a supporting rod. Different collision working conditions are disposed through electromagnetic valves, a collision force is transmitted to the transition shaft through a collision bearing block and the deformation rod so that the transition shaft and the bearing bracket generate a corresponding elastic vibration; when the collision force exceeds certain value, a slidingsleeve on the deformation rod moves, the deformation rod deforms so that the support rod deflects and the transition shaft is not supported. According to the device, by disposing the number, sequenceand current magnitude of the electrified electromagnetic valves, the collision rod is enabled to move and impact with the collision bearing block, different parts, impact forces and impact processed of the ships can be simulated, the collision force generated by the collision of the ships and the deformation of a hull when the collision force exceeds certain value can be further simulated, the working conditions of the actual collided ships are coincided so that the load borne by the tail shaft is closer to approach the real ship collision, and relatively scientific parameters are provided forshipbuilding and ship research in future.

Description

technical field [0001] The invention relates to an experimental device for a shafting of a ship, in particular to an experimental device for a shafting of a collision ship and a collision test method thereof. Background technique [0002] The working state of the ship shafting is affected by the state of the hull and changes within a certain range. The coupling and mutual influence among the ship shafting, stern bearing oil film and the hull are very prominent. Large ships are often subjected to various external loads during navigation to cause hull deformation, and hull deformation causes relative changes in the height of bearings at different positions in the shafting system, thereby changing the original alignment state of the shafting system, especially when the ship is in the process of During the collision, the hull is damaged due to a large external force. As the main propulsion system of the ship, the propulsion shafting of the ship will inevitably be affected durin...
