一个拟周期力作用下的船舶横摇模型的混沌解

Chaotic Solutions in a Ship Rolling Model with Quasi-Periodic Paratnetric Exciting Force

研究一个具有拟周期参数激励的船舶横摇模型的混沌解．应用一种改进的Ｍｅｌｎｉｋｏｖ方法，我们获得了该模型存在混沌解的参数条件．

In this paper, a ship-rolling model with quasi-periodic parametric exciting force is studied. By using a modified Melnikov method, we obtain parametric conditions under which rolling motion of the ship is chaotic.
