Title (EN) METHOD FOR HANDLING THROUGH-CHAMBERS WHEN CALCULATING WATERCRAFT DAMAGED STABILITY
(FR) PROCÉDÉ DE MANIPULATION DE CHAMBRES DE PASSAGE LORS DU CALCUL DE LA STABILITÉ ENDOMMAGÉE D'UNE EMBARCATION
(ZH) 一种船舶破舱稳性计算时贯通舱室的处理方法
Abstract:
(EN) A method for handling through-chambers when calculating damaged stability of a watercraft: virtually dividing a through-chamber (100) into multiple small chambers (101, 102, 103, 104) along a width direction of the through-chamber (100), and assuming water enters the multiple small chambers 101, 102, 103, 104) sequentially, until the watercraft achieves an equilibrium state. In this manner, when calculating damaged stability, it is only necessary to monitor a state of water entering the multiple small chambers (101, 102, 103, 104) when the watercraft achieves an equilibrium state, ensuring that a righting arm can have a positive value at each state, and it is not necessary to consider an overall state, avoiding analysis and monitoring of a great many intermediate states, saving calculation time and increasing calculation efficiency.
(FR) L'invention concerne un procédé de manipulation de chambres de passage lors du calcul de la stabilité endommagée d'une embarcation comprenant : la division virtuelle d'une chambre de passage (100) en de multiples petites chambres (101, 102, 103, 104) le long d'une direction de largeur de la chambre de passage (100) en partant du principe que l'eau entre dans les multiples petites chambres (101 102 103, 104) séquentiellement, jusqu'à ce que l'embarcation atteigne un état d'équilibre. De cette manière, lors du calcul de la stabilité endommagée, il est seulement nécessaire de surveiller l'état de l'eau qui entre dans les multiples petites chambres (101, 102, 103, 104) lorsque l'embarcation atteint un état d'équilibre, ce qui permet de garantir qu'un bras de redressement peut présenter une valeur positive dans chaque état, et il n'est pas nécessaire de prendre en considération un état global, d'éviter l'analyse et la surveillance d'un grand nombre d'états intermédiaires, de réduire le temps de calcul et d'augmenter l'efficacité de calcul.
(ZH) 一种船舶破舱稳性计算时贯通舱室的处理方法,沿贯通舱室(100)的宽度方向将贯通舱室(100)虚拟分隔为多个小舱(101,102,103,104),并假定多个小舱(101,102,103,104)按顺序依次进水,直至船舶达到平衡状态。这样在破舱稳性计算时只需对多个小舱(101,102,103,104)进水至船舶达到平衡时的状态进行监控,确保每个状态下的回复力臂为正值即可,无需考虑综合工况,省去了很多中间状态的分析和监控,节省了计算时间,提高了计算效率。
