双体采砂船结构有限元计算分析

Finite Element Analysis for Structural Strength of Dredger with Twin-hulls

对目前钱江水系采砂的双体工程船中的典型船进行结构有限元分析计算,根据计算结果分析其应力分布,特别是连接桥的应力分布状况,提出改型方案,并将改型前后连接桥结构强度的计算结果进行比较,证明改型方案的合理性。

： FE analysis was carried out for the structural strength of a typical inland river dredger with twin-hulls. According to the numerical results of the stress distribution in the structure, especially in the cross structure, a modification plan was proposed to the dredger. The comparative analysis of the structural strength of the dredger with twin-hull before and after modification verified that the plan is rational.
