The Optimization Design Research On Jib Arm Structure Of Giant Floating Crane Based On Genetic Algorithm

As ship design has a close relation with special capability implementation,building cost reduction, and some other important issues, ship design optimization isputting into use in the early time and develops rapidly. However, ship designoptimization in present time mainly focuses on a few aspects, such as ship sectiondesign considering ship hull longitudinal strength, and ship section design oncontainer ships with large hatch, while structure optimization designs of jib armstructure of giant floating crane are comparatively few. Nowadays, popular methodused in jib arm structure design is the conventional way based on criteria andarchetypal structures. With the great developments of large projects like deep-waterports, giant floating crane is badly needed. Therefore, engineers face the problem ashow to design huge floating crane economically, or how to improve existingengineering barges. Using the real engineering project, M500-700 tons floating craneas the background, this paper has studied the optimization design of the jib armstructure of M500, aiming to minimize the weight of the jib arm structure.This article mainly includes: taking lowest weight as optimization goal, criterionrequest as restrict, optimization programme on jib arm structure of giant floatingcrane design is written based on genetic algorithm;according to jib arm structure ofgiant floating crane which is being designed and other former ones, size and structureform of jib arm are deeply discussed, furthermore, relatively reasonable jib armstructure scheme is proposed.This subject has strong engineering background andapplication value,which can provide important data and referance for the design ofgiant crane framework for the future.
