The invention belongs to a ship body molded line control method in the technical field of ship manufacturing. The diameter D (1) of the outlet end of the sternpost and the diameter d (3) of the tail end of the stern shaft hub are not equal or the error exceeds a set range, and the horizontal distance L (2) between the outlet end of the sternpost and the center line of the rudderstock and the horizontal distance l between the tail end of the stern shaft hub and the center line of the rudderstock are not equal or the error exceeds the set range. If yes, modifying until the diameter D (1) of the outlet end of the sternpost is equal to the diameter d (3) of the tail end of the stern shaft hub or the error is within a set range, and the horizontal distance L (2) from the outlet end of the sternpost to the center line of the rudderstock is equal to the horizontal distance l (4) from the tail end of the stern shaft hub to the center line of the rudderstock or the error is within the set range. According to the ship body molded line control method, the problem of matching of the stern shaft hub and the ship body stern post outlet molded line is effectively solved in the ship body design stage, the hydrodynamic performance of the ship body molded line after ship manufacturing is completed is guaranteed, the installation requirement of the stern shaft is met, and the situation that the construction period is delayed and the cost is increased due to later modification is prevented.

    本发明属于船舶制造技术领域的船舶船体型线控制方法。艉柱出口端直径D(1)和艉轴毂尾端直径d(3)不相等或误差超出设定范围、艉柱出口端距舵杆中心线水平距离L(2)和艉轴毂尾端距舵杆中心线水平距离l不相等或误差超出设定范围,则修改直到艉柱出口端直径D(1)和艉轴毂尾端直径d(3)相等或误差在设定范围内、艉柱出口端距舵杆中心线水平距离L(2)和艉轴毂尾端距舵杆中心线水平距离l(4)相等或误差在设定范围内。本发明所述的船舶船体型线控制方法,在船体设计阶段就有效解决艉轴毂与船体艉柱出口型线匹配问题,保证船舶制造完成后船体型线的水动力性能,也满足艉轴安装要求,防止后期修改耽误建造周期及成本增加。
