The invention belongs to the technical field of ship construction, and discloses a lofting method which mainly comprises the following steps: establishing a side projection view of a hyperbolic bevel plate, and projecting a plurality of lower intersection points and a plurality of upper intersection points onto the side projection view; drawing a plurality of lofting lines of the lower bevel ribs; projecting the plurality of lower intersection points to a lofting line of the lower bevel rib to form lofting points of the plurality of lower intersection points, and sequentially connecting the lofting points of the plurality of lower intersection points to form a lower bevel lofting curve; projecting the plurality of upper intersection points to a lofting line of the lower bevel rib to form projection points of the plurality of upper intersection points; generating a lofting point of the upper intersection point corresponding to the projection point of the upper intersection point through the projection point of the upper intersection point; according to the lofting point of the upper intersection point, lofting points of all other upper intersection points can be obtained, and the lofting points of the multiple upper intersection points are sequentially connected to form an upper bevel lofting curve. According to the lofting method provided by the invention, the lofting precision can be effectively improved, the lofting deviation is reduced, the production efficiency is improved, and the cost is saved.
本发明属于船舶建造技术领域,公开了一种放样方法,其主要包括以下步骤:建立双曲线折角板件的侧面投影视图,将多个下交点和多个上交点投影至侧面投影视图上;绘制多个下折角肋的放样线;将多个下交点投影至下折角肋的放样线上以形成多个下交点的放样点,依次连接多个下交点的放样点以形成下折角放样曲线;将多个上交点投影至下折角肋的放样线上以形成多个上交点的投影点;通过一上交点的投影点生成与其对应的上交点的放样点;根据该上交点的放样点可得到其余所有上交点的放样点,依次连接多个上交点的放样点以形成上折角放样曲线。本发明提供的放样方法,能有效提升放样精度,减少放样偏差,提高生产效率,节约成本。
