摘要
文章通过Patran有限元软件,选取危险工况,对一实船船体结构的总纵强度进行了有限元直接计算,重点考察模型中完整舱主要结构构件的强度,然后与相关规范中的许用应力值进行比较。经强度校核后表明该船总纵强度符合规范要求,对确保航行安全具有实际意义。
According to the Guidelines,the longitudinal strength analysis of some operational ship in dangerous cases is carried out using FEM,based on the Patran software.The analysis of primary structural members of the complete cargo hold in the model is the key point.Finally the von Mises are compared with the permissible stresses.The strength assessment shows that the longitudinal strength of the ship complies with the requirements of the Rules,which is worthwhile for safety of shipping.
