船舶倾覆机理的新见解

利用“对振式可控力矩横摇装置”进行船模允许甲板入水的系列激振横摇实验，得到非线性横摇的实际而准确的数学模型，据此通过风浪联合作用下的动态横摇过程的数值模拟，探讨船模在横风横浪下的倾覆机理，从而形成新见解：翻船是动力横摇的极限运动，临界倾覆于高位平衡点稳定性的丧失。

NEW CONCEPT ON MECHANISM OF SHIP CAPSIZING

Using "The roll-exciter of the controllable moment with the type of contrary vibration", a series of forced rolling tests of deck into water are carried out. The realistic and exact mathematical model of ship nonlinear rolling is obtained. The capsize mechanism is researched by using the numerical simulation process of the capsize under the effect of wind and waves. Ship capsize is ultimate motion of dynamic rolling, the critical capsize results from the loss of stability under the high-state balanced position.
