摘要
"海豹6号"震源船由于设备布置需要,在船尾处加设一个悬尾结构。应船级社要求,悬尾与主船体连接处结构要进行直接强度验证。本文对该悬尾带来的结构不连续处的强度进行了简化船体梁法和有限元直接计算法分析。通过这2种方法的研究分析,分别对悬尾结构的抗弯、抗剪及抗扭强度有了整体的认识和局部细节的把握,证明了结构不连续处的弯曲和剪切强度符合要求,并对甲板吊支架非对称负重时可能产生的大扭矩等提出了使用限制。
To achieve the purpose of equipment arrangement,it needs to add hanging stern structure to "Seal 6"."Seal 6" is a kind of energy source boat.The strength of discontinuity which is brought by the hanging stern structure is analyzed with two methods:hull girder approach and finite element method(FEM).Through the analysis of the two ways,the strength of hanging stern structure contains shear force,bending moment and torque moment is calculated and realized.Also,some operations are advised to be prohibited because of large torque moment caused by unsymmetrical loads.
