摘要
采用MSC.Dytran软件对二维楔形体入水砰击过程进行数值模拟,分析考虑空气和重力因素的液面变化情况,总结入水速度、入水角度与砰击载荷的关系;对三维刚性船舶尾部结构入水砰击问题进行研究,得到曲率变化对结构砰击载荷的影响规律。
The slamming process of a 2-D wedge-shaped structure was simulated by MSC.Dytran. The change of liquid level considering the influence of air and gravity is analyzed, and the relationship between the velocity and angle of entry and the slamming pressure is summarized; Studied the 3-D rigid ship stern under slamming, the influence of the curvature change on the slamming pressure is obtained.
