摘　　要：目前,国际海事组织针对第2代完整稳性的制定工作已基本完成,过度加速度是其中5种失效模式之一。文章选取渔船和渔政船为母型船进行全参数化建模。通过改变水线面系数以及半进流角,进行船型变换,探究船体型线对过度加速度失效模式的影响,旨在提高两艘船的稳性。最终得出结论:水线面系数的增大会对过度加速度产生有利影响,半进流角的增大会对过度加速度产生不利影响,这可为船舶设计阶段提供参考。At present, the International Maritime Organization(IMO) has completed the formulation of the second generation intact stability, taking excessive acceleration as one of the five stable failure modes. the parametric modeling of the two mother ships namely the fishing vessel and the fishery administration vessel is carried out. By changing the waterline coefficient and the half angle of entrance, the ship shape is changed to explore its effect on the failure mode of excessive acceleration, which aims at increasing the stability of the two ships. It is concluded that the increase of the waterline coefficient has a beneficial effect on the excessive acceleration, while the increase of the half angle of entrance has an adverse effect on the excessive acceleration.this provide reference for ship design.
