摘要
本文应用非线性动力学理论 ,考虑船舶参数激励和横向强迫激励 ,研究了船舶的 1 /2亚谐共振运动。得到了横摇运动失稳条件 。
The 1/2 sub harmonic resonance motion of ships are studied using nonlinear dynamics theory. The stability lost conditions of rolling motion are obtained and the parameter regions of stability lost and capsize for ship rolling are presented when the ship is subjected to parametric excitaton and forced excitation of waves.
