摘要
目的 快速准确计算波浪诱导的船载重大件货物的运动趋势,提升船舶航行安全.方法 基于直接计算方法,考虑船舶自由度运动耦合效应、相位变化及摩擦力的有利影响,提出一种船载重大件货物的运动趋势直接计算方法.进一步开展21000TEU集装箱船在不同航行工况、不同装载位置处的货物运动趋势及惯性载荷研究,并与劳氏船级社的规范结果进行对比分析.结果 货物横向滑移多发生于横浪或最大横摇运动工况,纵向滑移和翻转多发生于迎浪且船艏处垂向力过小工况.该方法计算结果准确可靠,计算效率高.结论 研究成果可以为船载重大件货物的绑扎系固以及安全性校核提供指导,具有一定的工程实用价值.
Abstract
The work aims to quickly and accurately calculate the multi-motion trend of major cargoes on ships induced by waves,and improve the safety of ship navigation.A direct calculation method for multi-motion trend of major cargoes on ship was proposed based on the direct calculation method by taking into account the coupling effects of ship motion,phase changes and the beneficial effects of friction.Further researches were conducted on the multi-motion trend and inertial load of cargoes on the 21000TEU container ship under different navigation conditions and loading positions,and the comparative analysis was conducted with the criteria results of Lloyd's Register of Shipping.The lateral slippage mostly occurred in the condition of transverse waves or maximum roll motion,and the longitudinal slippage and flipping mostly occurred in the condition of facing waves and too small vertical force at the bow of the ship.The method was accurate and reliable,with high calculation efficiency.The results can provide a certain reference for the binding and fastening of major cargoes,as well as safety verification,and have certain engineering practical value.
