基于三维参数的船舶稳性设计与优化研究
|
摘要
据国际统计数据表明,大量船舶事故的主要原因是船舶的失稳,进而导致船舶失控,发生事故。近年来,基于三维参数化软件的船舶优化设计成为了一项热点研究,并取得了相当可观的研究成果。为了提高船舶的稳定性,保障船舶航行的安全可靠,本文建立了船舶的稳性数学模型,进行船舶的稳性计算,并结合三维设计软件平台CATIA对船舶进行参数化建模,最后利用CATIA的二次开发,完成了船舶稳性设计与优化的仿真试验。试验表明,基于三维参数化的船舶稳性设计具有良好的效果,应用潜力巨大。
According to international statistical data, the main cause of a large number of ship accidents is ship instability, which leads to ship out of control and accidents. In recent years, ship optimization design based on 3D parametric software has become a hot research topic, and considerable research results have been achieved. In order to improve the stability of the ship and ensure the safety and reliability of navigation, this paper establishes a mathematical model of ship stability,calculates the stability of the ship, and parameterizes the ship with the three-dimensional design software platform CATIA.Finally, the simulation of ship stability design and optimization is completed by the secondary development of CATIA. Experiments show that the ship stability design based on three-dimensional parameterization has good effect and great application potential.
