The invention relates to the technical field of ship structures, and discloses a linear construction method of a cast steel and forged steel combined stern shaft package structure and the structure thereof. The construction method comprises the following steps that a basic linear structure is determined, a hyperbolic equation is determined, a second comparison linear structure is constructed, a third comparison linear structure is constructed, strength optimization analysis of different linear structures is carried out, and welding is carried out after the optimal linear structure of a stern shaft package structure is determined. A better stern linear structure is found out, the manufacturing process is good, more flexible welding forming of a stern shaft package and a cabin is facilitated, the hyperbolic curve is selected as the line type of the forged steel part for the stern shaft package structure, when the stern shaft package structure is impacted by fluid, the energy of the fluid can be better transferred to the left rear part, and the forged steel part has better impact resistance; the impact energy can be well released, the stern shaft package structure has better structural rigidity, and most structures of the stern shaft package are made of forged steel parts, so that the weight is lighter.

    本发明涉及船舶结构技术领域,公开了一种铸钢与锻钢组合型艉轴包结构的线型构造方法及其结构,构造方法包括以下步骤:确定基础线型结构、确定双曲线方程、构造对比线型二、构造对比线型三、进行不同线型结构的强度优化分析、艉轴包结构确认最优线型后焊接,本发明线型构造方法,对锻钢件的不同线型计算了船艉结构强度,寻找出较优的船艉线型结构,制造工艺良好,方便艉轴包和舱室更灵活的焊接成型,艉轴包结构选择双曲线为锻钢件的线型,当受到流体冲击时可以较好的将流体的能量向左后方转移出去,锻钢件具有较好的抗冲击性能,能够较好的将冲击能量释放出去,艉轴包结构具有更好的结构刚度,且艉轴包大部分结构采用了锻钢件,具有更轻的质量。
