固体火箭发动机粘接界面剪切蠕变特性分析与快速预测模型
Characteristic analysis and rapid prediction model of shear creep at bonding interface of solid rocket motors
摘要
Abstract
During vertical storage of solid rocket motors,shear creep behavior occurred at the sidewall bonding interface due to self-weight load,threatening the structural safety and storage life of the motor.To study the shear creep characteristics of the bonding interface,shear creep tests were conducted on a certain motor shear interface test piece under various temperatures and stresses,and the shear strain-time relationship was obtained.The response and regularity of the mechanical properties of the bonding interface to temperature and shear creep load changes were analyzed,and a rapid prediction model for the shear creep of the bonding interface in the linear viscoelastic stage was finally constructed.The results show that the rapid prediction model is simple to construct and the difference between the predicted value and the experimental value is less than 10%,and it can predict the short-term creep behavior of the adhesive interface in the linear viscoelastic stage.关键词
