本文通过模型试验研究了浸水船舶在波浪中的非线性横摇运动。研究发现，即使在中等振幅的规则横浪中，浸水船舶的横摇响应也会表现出不规则的复杂特性。非线性分析表明，它们可能是混沌的。恢复力矩的非线性和洪水的动力效应导致了这种复杂的运动。
This paper investigates the nonlinear roll motion of a flooded ship in waves using model experiments. It is found that roll response of a flooded ship can exhibit irregular and complicated behavior even in regular beam waves with moderate amplitude. Nonlinear analyses indicate that they can be chaotic. Nonlinearity in the restoring moment and dynamic effects of flooded water cause this complicated motion.
