船舶气囊下水运动受力计算及结构强度分析

船舶气囊下水是我国独创的工艺,气囊下水工艺在中小型船舶下水中应用尤为广泛。随着采用气囊下水船舶尺度的增大,下水过程中的不确定因素增多,船用气囊下水的风险也随之增大,因此要解决下水安全问题,就必须不断提高气囊的承载能力和制定更加合理的下水方案。而如今气囊下水多是利用经验进行操作,存在一定的事故隐患,因此运用数值仿真的方法研究气囊下水具有重要的意义和应用价值。

Gasbag launching stress calculation and structure strength analysis of ship Bian Mingyu

Ship gasbag launching is the original technique in our country,widely used in middle and small ship launching. With the scale augment of adoptinggasbag launching ship,the uncertainty factors increase during launching,the risk of ship gasbag launching increases ,so we must improve the carrying ca-pacity of gasbag constantly and establish more logical launching scheme for settling launching safety problem. But the gasbag launching mainly operated u-sing experience now,being some accident threat,so research on gasbag launching using numerical simulation method has important meaning and applicationvalue.
