【摘要】：針對當(dāng)前船體分段翻身方案設(shè)計(jì)中存在的可靠性不高、經(jīng)驗(yàn)設(shè)計(jì)為主等問題,綜合經(jīng)濟(jì)性和安全性進(jìn)行優(yōu)化設(shè)計(jì)研究。首先,對分段吊平面上的吊點(diǎn)進(jìn)行適應(yīng)度評估,初步確定眼板數(shù)量,得到一系列的吊點(diǎn)布置組合方案。其次,以吊裝過程中分段的總體應(yīng)變能最小為優(yōu)化目標(biāo),綜合吊裝過程中的約束進(jìn)行最優(yōu)化建模。再次,引入粒子群優(yōu)化算法,并借助Matlab和Ansys軟件的數(shù)據(jù)交互,以實(shí)現(xiàn)吊點(diǎn)位置的最優(yōu)化設(shè)計(jì)。最后,根據(jù)吊點(diǎn)位置和分段結(jié)構(gòu)得到各吊點(diǎn)所布置眼板的類型和承載能力。
[Abstract]:In order to solve the problems of low reliability and experience design in the design of ship hull section turning scheme, the optimization design is studied based on economy and safety. Firstly, the fitness of the lifting points on the plane of the segmented suspension is evaluated, and the number of eye plates is preliminarily determined, and a series of combination schemes for the arrangement of the lifting points are obtained. Secondly, the optimization model is based on the constraints in the hoisting process, taking the minimum total strain energy of the segment in the hoisting process as the optimization objective. Thirdly, the particle swarm optimization algorithm is introduced, and the data interaction between Matlab and Ansys software is used to realize the optimal design of the lifting point position. Finally, the types and bearing capacity of the eye plates arranged by the lifting points are obtained according to the location of the lifting points and the segmental structure.
