Side-bend energy absorbing buffer stem

Abstract

The invention discloses a side-bend energy absorbing buffer stem, which comprises a hull. A longitudinal structure unit, a transverse structure unit and an advanced collapsing structure are arranged in the hull, wherein the longitudinal structure unit is provided with a horizontal stringer, and the advanced collapsing structure is provided with a plurality of collapsing portions which are arranged at junctions of the horizontal stringer and the hull. When the buffer stem bumps a collided ship, the collapsing portions can collapse in advance and enable the buffer stem to deform in a side-bend manner, accordingly, the contact area of the buffer stem with the collided ship can be increased, impact force can be scattered, and the buffer stem is prevented from puncturing a hull of the collided ship.

Description

technical field [0001] The invention relates to a cushioning bow, in particular to a side-bending and collapsible cushioning bow. Background technique [0002] When a ship collides with an accident, in order to prevent the bow of the ship involved in the accident from breaking through the hull of the ship being hit, resulting in oil leakage inside the ship being hit and causing serious pollution to the environment, there is currently a study on the design of a cushioned bow. Please refer to figure 1 As shown, it is a schematic diagram of the internal structure of an existing cushioning bow. The existing cushioning bow has a hull 1, and the hull 1 is provided with a centerline girder 2, two horizontal girders 3 and other vertical longitudinal girders. Strong structure, and a transverse rib system 4, a plurality of sternal ribs 5 and other transverse strong structures, through which when the existing cushioning bow is hit in a forward direction, since most of its structure is...

[0003] However, the impact energy absorbed by the structure collapse of the buffer bow has its limit. For large or high-speed ships, the energy absorbed by the structure collapse of the buffer bow alone may not be enough to offset the entire collision accident Therefore, some researchers have proposed some methods to make the bow prone to side bending deformation, such as lengthening the bulbous bow or reducing the section of the bulbous bow root, etc., through this, when the ship involved in the accident is obliquely When hitting the ship being hit, or when the ship being hit has a forward speed, the bow of the ship that caused the accident will bend sideways due to the lateral force, which can greatly increase the contact area between the ship that caused the accident and the ship that was hit. The bow of the ship that caused the accident will not penetrate the hull of the ship that was hit, but whether the method of lengthening the bulbous bow or reducing the section of the root of the bulbous bow will seriously affect the hydrodynamic performance of the ship, and many Criticized by the industry
