摘要: 介绍了一种新的系留缆绳接头结构。利用有限元分析方法,使用试验中常用的正交设计分析方法,研究了底面圆直径、胶体高度、胶体锥角三种几何因素在取不同水平条件时对系留缆绳灌胶接头强度的影响。分析结果表明,三种因素对灌胶接头应力都有显著影响,其中以胶体高度对其影响最为显著,底面圆直径次之,锥角影响较小。

Abstract: A new tether joint structure is introduced, which utilizes finite element method (FEM) and orthogonal design method widely used in experiments to figure out how the three geometric factors (bottom circle diameter, glue height, and taper angle) exert influences on the bonding joint strength under different level conditions. The results show that all the three factors have significant effects on the bonding joint stress, of which the influence of glue height is the largest, bottom circle diameter less and taper angle the least.

Key words: tether, epoxy resin, geometry, finite element method (FEM)
