| 摘 要： | 分析了小水线面船搁浅研究的方法,描述了小水线面船的搁浅模式,采用有限元方法对小水线面船搁浅问题进行了数值仿真计算.计算结果表明,从能量角度出发,小水线面船搁浅过程中各构件所吸收的能量不同,外板和横框架是最主要的吸能构件,其次是纵骨,而舱壁板吸收的能量最少.因此,在考虑提高小水线面船的抗搁浅性能时应从加强外板和横框架开始.

| Abstract: | A method to simulate the grounding of a SWATH is investigated.The grounding pattern of a SWATH is described.The grounding of a SWATH is simulated numerically by FEM.The simulation results show that the energy absorbed by each component differs from each other during the grounding.The shell and the transverse frames absorb the most energy,while the longitudinal frames absorb less.The bulkhead plate absorbs the minimum.Therefore,the shell and transverse frames are those components that should be strengthened ... |
