摘要
T型焊接接头在船舶与海洋工程结构中广泛应用,研究T型焊接接头的疲劳性能对于提高船舶与海洋工程结构的强度具有重要意义.针对工程中常用的四种焊趾形式的T型焊接接头,利用有限元计算和模型试验两种方法对其疲劳性能进行了研究.结果表明,平面型焊趾是较优的T型接头焊趾形式.
T shape joint is used widely in the ship and marine engineering structure. The research of its fatigue performance is significant to enhancing the strength of ship and marine engineering structure. The fatigue performance of four kinds of common used weld toe is studied by the FEM and experiment method. The results indicate that the line type weM toe is the preferable T shape joint type.
