摘要/Abstract

摘要： 基于外部碰撞力学及碰撞分析理论,分析长江内河流域小型液化天然气（LNG）运输船被其他船只以不同速度、碰撞角及受撞击点碰撞下的能量损失。从外部动力学角度出发,计算LNG运输船在运行过程中与其他船舶相撞时能量损失情况,为LNG运输船内部动力学分析奠定基础。

Abstract: Based on the external collision mechanics and collision analysis theory,this paper analyzes the energy loss of small LNG carriers in the Yangtze River Basin when colliding with other ships at different speeds,collision angles,and impact points. From the perspective of external dynamics,the energy loss of LNG transport ships when colliding with other ships during operation is calculated,which lays the foundation for the internal mechanical analysis of LNG ships.

Key words: LNG carrier, ship collision, energy loss, external collision mechanics
