摘　　要：针对玻璃钢定向器的老化性能及蠕变行为,提出了相应的蠕变估算方案。通过试验曲线对比验证,建立适合定向器用玻璃钢材料的本构模型;对Schapery、Rabotnov两种蠕变理论进行深入研究,利用蠕变试验曲线确定模型中的相关参数,拟合两种模型的蠕变变形图,结果表明:Rabotnov蠕变理论更适合用于描述定向管用玻璃钢材料的蠕变变形。Aiming at the aging properties and the creep behavior of glass-steel launching tube, this paper proposed a corresponding creep estimation scheme. By contrasting the test curve, we built the constitutive model for the non-metallic launching tube material. To conduct the thorough research on the Schapery and Rabotnov creep theory, we determinated the related parameters in the model by using the creep test curve and fitting the creep deformation of two models. The results show that the Rabotnov creep theory is more suitable to describe the creep behavior of glass-steel launching tube.
