摘要： 阐述了全船有限元结构强度分析的直接计算流程和方法，以6 000 t甲板驳船为例，对其中的若干关键技术，如甲板货物的不同模拟方法（虚梁法、多点约束法和质量点法）及剖面荷载参考点的选取等进行了研究，提出了相关建议.在此基础上，实现全船的结构强度评估，以期对全船有限元结构分析中相关关键技术的应用提供一定的参考.

Abstract: A 6 000 t deck barge was taken as an example to expound the process of direct calculation method of the wholeship FEA. Efforts were being made especially on several key technologies such as the different simulation methods of cargoes loaded on the deck (virtual beam method, multipoint constraints method and mass point method), the selection of bending moment and torque reference point on the section, etc. Furthermore, some recommendations were put forward, based on which the global structural strength evaluation was achieved. This research will provide certain reference for the application of relevant critical technologies in the wholeship structural analysis through FEM.
