钢玻复合船体结构中钢与玻璃钢螺栓连接接头形式分析

Analysis of Bolted Joint Form between Steel and FRP in Steel-glass Composite Hull Structure

针对当前复合材料上层建筑与钢质主船体之间螺栓机械连接形式Π形接头和L形接头的强度较弱、易发生损坏的问题,从增强复合材料接头强度角度,提出一种加强L形接头,进行相应的拉伸试验和数值仿真计算,并将其与现有的Π形接头、L形接头进行对比,结果表明,加强L形接头的强度更好。

Aiming at the problems of weak strength and easy damage of∏-joints and L-joints in bolt mechanical connection between composite superstructure and steel main hull,a kind of reinforced L-joint was proposed to enhance the strength of composite joint.The corresponding tensile tests and numerical simulation were carried out.Comparation of the numerical results with that of the existing∏-joints and L-joints showed that the strength of reinforced L-joint is better.
