摘要
本文考虑船舶横摇与纵摇的非线性耦合运动，采用摄动分析及数值计算方法，研究了船舶存在内共振时的非线性动力学行为。研究表明，船舶非线性运动的重要特征是响应不对称、调幅调相及饱和等现象，为揭示船舶在高海情下的倾覆机理奠定了基础。
An analysis is presented for the nonlinear coupling of the pitch and roll modes of shipmotions in regular seas. The dynamic behavior of ships' internal resonance is studied withperturbation method and numerical calculating method. The results indicate that the important characteristics of ship nonlinear motions are asymmetric response, amplitude- andphase-modulated motion, and saturation phenomenon. The research forms the foundationfor revealing the capsize mechanism of ships in rough sea.
