SU1088982A1 - Corrugated board plating of ship hull - Google Patents

Description

one

The invention relates to shipbuilding and can be used in the design and modernization of high-speed vessels.

Existing types of modern high-speed vessels experience significant shock loads on the bottom of the ceiling when moving on a rough surface,

The known sided corrugated hull of the ship hull consists of a flat panel with a pleated insert, the corrugations of which are arranged parallel to the deck of the ship Q.

However, such a structure does not have the ability to reduce the effective loads when driving on waves due to the rigid fixing of all connections, which leads to damage to the structural elements.

The purpose of the invention is to increase the elastic characteristics of the side plating, as a result of which the damage to the bottom plates of the hulls of high-speed vessels during movement in waves due to the reduction of external loads acting on the structure is reduced.

To achieve this goal, the design of the onboard corrugated siding, consisting of a flat panel with a corrugated insert, the corrugations of which are parallel to the deck of the vessel, is provided with half-tangles fixed on the said panel.

In this case, the corrugated insert is installed along the entire length of the bead, starting from 1/4 of it from the bow of the vessel, and the corrugations of the insert are filled with elastic material.

Fig, 1 schematically shows the mid-frame of the proposed core 889822

Pusa ship; in fig. 2 - node I in figure 1,

The design contains a bottom casing 1 with 5 longitudinal stiffening ribs 2 fixed on it, on which flora 3 rests, fixed on the onboard casing 4. The casing 4 has higher than 3 flora a longitudinal corrugated insert 5 with corrugated rubber 6. inserts 5 side trim 4 is supported by stringer 7 and half-gang 8, which are connected

15 with a beam 9.

When moving along an agitated surface, a hydrodynamic impact is perceived by the plates of the bottom shell 1 and attached to it.

20 longitudinal ribs 2 stiffness, is transmitted to 41 holes 3, mounted on the side casing 4. Further, a significant part of the impact energy is absorbed by the side longitudinal corrugated inserts 5 and damping aggregate 6, and the rest is transmitted through half-bar B to beam 9.

In connection with the absorption of energy by UD3Q ra longitudinal side corrugations.

the impact load from the hydrodynamic impact perceived by the bottom overlap will be higher, and the overlap plates will not receive significant residual deflections due to a decrease in the dynamics and peak loads during the impact. In general, an increase in the bottom plate compliance will reduce the loads that the hull of a high-speed vessel is experiencing in rough seas, and 13CHARGES to operate it at higher travel speeds without reinforcement or reinforcement of the structure.
