| 摘 要： | 为了研究高腹板梁在碰撞过程中的剪切破坏机理,提高对船舶结构碰撞吸能的认识,文章从某油轮舷侧截取典型结构单元——带板梁作为研究对象,基于极限平衡理论和LS-DYNA软件对其碰撞破坏过程进行分析。研究带板梁极限载荷、最大挠度和最大吸能影响因素和计算方法,同时分析弯曲应变能和膜应变能占总吸能的比重。结果表明：单元尺寸和材料极限塑性应变对带板梁的最大挠度和最大吸能都有显著影响;膜应变能和弯曲应变能在带板梁破坏时所占比重相当。

| Abstract: | In order to research the shear failure mechanism of beam with high web plates and enhance understanding on the absorbing energy in the ship collision,the structure of a beam with band plates was chosen as example to study the typical structural elements from broadside on oil tanker.Utilizing the ultimate equilibrium theory and LS-DYNA software,the energy absorting mechanism of the beam due to collsion was analyzed,with attention particularly to the effect of plastic hinging charateristics of beam with band ... |
