大开口船舱口梁连接处应力集中的有限元分析

Finite Element Analysis for Stress Concentration at Connecting Point of Transverse Deck Beam on Large-Opening Container

本文对一集装箱船(1:10)钢模的抗舱口扭转变形甲板箱形梁在连接处的应力集中问题,取几种不同的连接形式,用SAP5程序进行有限元分析。通过对应力集中系数的比较,提出了较为合理的连接形式。

This paper makes a finite element analysis for stress concentration at the connecting point of the transverse deck beam, which is in torsional deformation, by using SAP5 structure analysis programme. The model is a steel model of a large-opening container(1:10). And the paper shows a reasonable connecting form by comparing stress concentration coefficients.
