V型船应用气囊上下水的力学分析

Mechanical Analysis of Launching of the V-Shaped Ship Using the Gasbags

针对V型船应用气囊上下水的方案,建立了气囊变形模型,对船体各站点处的气囊变形、气囊布置位置处的支撑面积、气囊变形后的体积变化等进行了计算,求得了气囊的支撑力和力矩,并对上下水过程中船体的力矩平衡状态进行了分析。

According to the drawing lines of the V-shaped ship, the curved surface of the ship is constructed. The Model of cross section transformation of the gasbag in launching of the V-shaped ship is established. By means of the curve of drawing lines at every square station of the V-shaped ship, the width ofgasbag＇s cross section at different height can be calculated, and the transformation of the gasbags, the loading area of the gasbags and the change of the volume as a result of transformation of the gasbags are calculated and analyzed The loading of the gasbags and the balance of the moment of the ship in launching process are discussed.
