摘要
针对大型船舶上层建筑整体吊装过程中的变形控制问题,以某大型VLCC为研究对象,利用MSC.Nastran有限元软件对其上层建筑结构进行整体吊装强度有限元分析,得到各层结构响应,据此提出结构加强措施,有效降低了结构应力和变形。
Aiming at the issue of deformation control during superstructure integral hoisting of large ships , the MSC.Nastran software is utilized to carry out the FE analysis for a large VLCC′s superstructure .According to the characteristics of the re-sponse , a reasonable and effective method of structure reinforcement is put forward , by which the response of stress and displace-ment during the hoisting goes down to a safe level .
