有限元程序在重特大件运输中的运用

Applications of FEM Program in Heavy Cargo Transportation

以一艘载重15 000 t的大型半潜式甲板驳船(重任1602)装载4个超大型沉箱为例,采用直接计算法,利用国际上相关成熟的有限元程序(Ansys),进行局部结构强度计算,并对计算结果进行了分析和评估,提出了操作和结构加强建议。

With the help of the international widely-used FEM program ANSYS, the paper adopts the Direct Strength Method (DSM) to calculate the local structure strength of a large semi- submergible deck barge (Zhongren 1602) whose carrying capacity is15000 tons with 4 super large caisson on it. The paper analyses and evaluates the result and brings forward some suggestions about operation and structure reinforcement. [
