摘　　要：该文首先依据原1 700dwt驳船的结构形式,按照《钢质内河船舶建造规范(2012)》的要求,重新设计改造成1 500dwt散装水泥转运趸船并确定各构件的尺寸。然后使用MSC.Patran软件建立全船有限元模型,按照新设计的尺寸赋单元属性,按照不同工况下载荷组合不利的原则施加载荷,使用MSC.Nastran软件进行屈服强度分析,计算得到了该船典型工况下的应力分布及变形响应情况。结果表明,采用全船结构强度直接计算的方法是可行、可靠的。In accordance with Rules for Construction of Inland Steel Ships 2012, the 1 700 dwt barge is redesigned and transformed into a 1 500 dwt bulk cement carrier, then sizes of the components are determined. The finite element model of the whole ship structure is es- tablished by MSC. Patran. The element property is set up with the redesigned size. Base on the most dangerous load combination in different operating conditions, the load is applied. The yield strength is analyzed by MSC. Patran. Then the stress distributions and deformation responses in typical operating condition are calculated. The result shows that the method of direct calculation on whole ship structure is feasible and reliable.
