摘　　要：基于ITTC推荐的参数横摇运动方程,采用估算方法确定方程中的阻尼系数和复原力矩系数,数值模拟出船舶在规则波中的参数横摇情况,将上述方法具体应用于一艘滚装船船模的参数横摇预报,并与试验数据进行对比,验证了所采用方法的有效性。A numerical simulation method based on ITTC recommendation was used to investigate the occurrence and magnitude of parametric rolling in longitudinal regular waves. The approach for empirical calculation of roll damping and fast simulation of nonlinear GM variation was presented. The comparison of the numerical results of the parametric rolling prediction for a Ro-Ro ship with the model test results validated the employed method.
