Research On Rigid Securing Of Ship Unloader Based On ANSYS

The advancement of science and technology has greatly improved the capacity of China's machinery manufacturing.At the same time,with the implementation of the One Belt One Road policy,the marine safety of exporting large machinery has become the focus of the shipping industry.Ship unloader is one of the important equipments of bulk cargo terminal.Its efficient unloading capacity and operation stability play an important role in port loading and unloading.However,today's ship unloaders are very large in mass and volune,and their own structure makes the appearance extremely irregular.Therefore,in terms of the safe transportation of shipboard exports,the safety and reliability of 'the securing and lashing schemes have always been the focus of attention.The ship-mounted ship unloaders mainly use deck barges to transport the ship unloaders.Although the towed deck barge itself has power,and the ship unloader has a high center of gravity and a large volume,the traditional securing method using flexible lashing or rigid-flexible mixing can no longer guarantee safety,so most of them use rigid securing for marine transportation.This article will be based on this scheme design and optimization of various securing methods are used to study the transportation of the grab ship unloader.This article takes the safe transportation of towed deck barges to grab ship unloaders as the research object,and analyzes and researches from the four angles of material selection,design,verification and optimization of rigid lashing schemes.In terms of material selection,introduce common types of rigid materials,and use the principles of rigid materials for securing schemes for material selection;collection of materials for the design of securing strapping schemes;combining knowledge of material mechanics,using the ANSYS software for statics Partial modeling is used to check the securing scheme;in the case of ensuring safe transportation,the multi-objective genetic algorithm in the software is used to lighten the main components of the securing and binding,reduce the transportation cost,and unload the towed deck barge.Marine aircraft has important practical significance.The conclusions of this article can be extended to the transport of other similar large cargoes by deck barges,and it also provides reference and reference for the relevant shipping companies to formulate rigid lashing schemes for transporting corresponding ship unloaders.
