摘要
室温时测定了EP(环氧树脂)胶体试件、EP胶粘剂/不锈钢胶接件(对接结构试件)在不同载荷作用下的单轴蠕变特性,并采用黏弹性多重积分Onaran模型对上述两种试件的蠕变性能进行了模拟。研究结果表明:对接结构试件与EP胶体试件相比,前者的蠕变现象比后者明显;当两者的蠕变行为相差最大时,前者的初始应变、最终应变分别比后者增加了19.92%、17.92%;黏弹性多重积分Onaran模型能很好描述两种试件的蠕变行为,并且该研究结果可作为对接结构疲劳分析等后续研究的基础。
The monopodium creep properties of epoxy resin （EP） gel sample, EP adhesive/stainiess steel glue joint（docking structure sample） at room temperature were measured under the action of different loads. And the creep properties of the above two kinds of samples were simulated by visco-elasticity multiple integrals Onaran model. The research results showed that the docking structure sample compared with EP gel sample, the creep phenomenon of the former was more obvious than that of the latter. When the difference of both creep behavior was biggest, the initial strain or ultimate strain of the former were increased by 19.92% or 17.92% than those of the latter. The viseo-elasticity multiple integrals Onaran model could well describe the creep behavior of two kinds of samples, and the research results could be used as post-investigation＇ s basis for fatigue analysis of docking structure.
