船型参数对参数横摇薄弱性衡准的影响

Influence of Ship Type Parameters on Parametric Rolling of Vulnerability Criteria

参数横摇是第二代完整稳性衡准五大失效模式之一.为了研究新衡准对船舶设计带来的影响,选择了渔政船,渔船,集装箱船,散货船四种类型共六种母型船,在每种母型船的基础上,利用CAESES软件改变其垂线间长、型宽、型深和水线面系数等船型参数进行系列变形,生成136艘新船型,分别进行参数横摇薄弱性衡准计算,得到船型参数对参数横摇薄弱性影响的规律,为新船型开发设计提供理论依据.

Parametric rolling is one of the five failure modes of IMO 2nd generation intact stability criteria.In order to study the influence of new stability criteria on ship design,six types of parent ships of fishery administration ships,fishing boats,container ships and bulk carriers were selected.On the basis of each type of parent ship,the parameters of vertical line length,shape width,shape depth and waterline surface coefficient were changed by CAESES software.136 new ship types were generated.The parameter roll vulnerability standard calculation was carried out respectively,and the rule of ship type parameters'influence on parameter roll vulnerability was obtained,which provided a theoretical basis for the development and design of new ship types.
