摘要: 为解决自底向上逐一生成舱室的分舱方法需要花费大量时间, 提出了一种自顶向下的船舶参数化分舱方法, 利用舱壁位置参数与内壳折点位置参数驱动生成分舱理论面, 再用分舱理论面切割主船体, 利用非流形造型技术及其布尔运算生成舱室。分析结果表明: 该方法只需舱壁位置与内壳折点信息, 即可进行参数化分舱, 避免了大量舱室型值信息的输入, 降低了舱室定义的复杂性; 通过非流形造型记录了分舱时的过程信息, 修改模型时只需对这些信息重组即可, 实现了分舱模型的快速重塑。可见, 该方法能够快速实现船舶分舱与舱容计算, 为船舶三维参数化设计奠定了基础。Abstract: In order to solve the time consuming disadvantage of bottom-up subdivision method generating all compartments one by one, a new parametric top-down subdivision method was proposed. The parameters of bulkhead positions and inner knuckle positions were used to generate the subdivision planes to cut main hull. The non-manifold modeling technology containing Boolean operations was applied to generate compartments. Analysis result shows that the parametric subdivision is realized by taking bulkhead positions and inner knuckle positions as the only inputs, the complexity of compartment definition reduces because of avoiding the fussy input of compartments' offset. The non-manifold modeling maintains the whole process information so that the compartment models can be modified quickly by restructuring the information.So the subdivision and calculation of hold capacities can be finished rapidly by the method, which lays the foundation for 3D parametric design of ship.
