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. 3 tabs, 15 figs, 15 refs.
