摘　　要：在无码头的情况下,利用集装箱船改装后的渡海输送登陆栈桥系统,具有装卸载不依赖吊装设备的优点,使登陆栈桥系统能够迅速展开和拼装。在缺乏港口屏蔽的海浪环境中,登陆栈桥系统进行卸载,必须考虑波浪对船的作用和登陆栈桥系统与船的相互作用。利用浮基多体系统动力学方法,考虑海况、船型和登陆栈桥系统在船上运动参数等因素,计算了各工况下的横摇运动响应,进而给出了登陆栈桥系统安全卸载的操作要求,对集装箱船改装可行性提供了理论支持。The commercial containerships are used to transport the Landing Trestle Bridge System （LTBS） without the dock. It is great in numbers and independent of cargo handling gear in unload process. The LTBS can be deployed and assembled in elevated sea state conditions up to and including sea state three, Given the LTBS unload without reject of port, consideration must be taken of the effects on ship by wave and the coupling interaction of ship and LTBS, In this paper, the dynamic equation of wave-floating base-LTBS system is obtained by dynamic method of multi-body system with a floating base. Wave, type of ship and motion of the LTBS on the ship are considered and rolling responses in some conditions are presented. This research can provide effective reference to the feasibility of the commercial containership refit.
