Anti-collision method of ship made of composite materials and hull structure

Abstract

The invention discloses an anti-collision method of a ship made of composite materials and a hull structure. The invention is mainly characterized in that sandwich plates (12) made of the composite materials are used as the outer walls of the hull, an integrated anti-collision bulwark (1) is adopted, the hull is in a 'cage type' structure, annular reinforced ribs are arranged on the side surfaces of the hull, and an energy-absorbing bow is adopted. The hull structure has the characteristics of light weight and high strength, and simultaneously, the overall anti-collision performance of the ship made of the composite materials is effectively improved through the comprehensive anti-collision structure design. When the ship has a collision on a front surface or a side surface, the comprehensive passive safety protection hull structure provided by the invention can effectively buffer an impact force caused by the collision of the ship, has good energy-absorbing effect and strong anti-deformation capacity, and is favorable for preventing or reducing casualties and property loss caused by the collision of the ship. The invention is especially suitable for the anti-collision design of the ship made of composite materials and has better application and popularization prospects.

Description

technical field [0001] The invention relates to an anti-collision method and a hull structure of a boat, in particular to an anti-collision method and a hull structure of a composite material boat, which are mainly used in the field of composite material boat manufacturing. Background technique [0002] With the continuous development of the maritime transportation industry, there are more and more collision accidents between ships. According to the analysis of maritime data, more than 40% of the shipwrecks in the world are caused by ship collisions. Such incidents often cause losses in ship structure, service life, safety performance, etc., and even cause serious tragedy of ship crashes and human deaths. For official duties such as law enforcement, patrol, sniping, rescue, etc., especially when conducting random inspections, hunting and intercepting illegal ships, hull collisions are the most likely to occur, and ships for such purposes inevitably bear the risk of mutual c...

AI Technical Summary

Problems solved by technology

At present, the design and research on the passive safety performance of composite material boats are relatively rare. The hot spots of people's research and development are only concentrated on the anti-collision fenders, and the design concept is relatively simple. Most composite material boats have poor anti-collision performance. The overall safety protection is not enough, and some boats even completely ignore it

However, from the perspective of hull structure, there is almost no research on improving the overall anti-collision performance of composite hull structures in all directions.
