| 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. |
