摘要
考虑阻尼力矩和恢复力矩的非线性,运用能量法对正横规则波中船舶非线性横摇运动方程进行等效线性化,导出等效线性系数表达式,并验证其工程实用性,为船舶横摇预报提供理论分析计算模型。
Considering the nonlinearity of damping and righting moment,this paper studied the equivalent linearization of the nonlinear rolling equation of ship in the regular transverse wave by applying the energy method,the expression of the equivalent linearization coefficient is derived,and its engineering practicability is checked,which provide the theoretical analysis and calculation model for the prediction of ship nonlinear roll motion.
