固体火箭发动机的粘接界面通常在贮存和使用过程中容易受到多种环境因素的影响。采用加速老化的方法研究钢壳体发动机粘接界面在湿热老化条件下的性能变化。双因素显著性分析可对界面扯离力的测试影晌进行量化评估。结果表明湿热环境下界面力学性能下降明显,湿度变化为主要原因。
Solid rocket motor bonding interface is usually stored and used in the process susceptible to a variety of environmental factors. The method of accelerated aging was used to study the change of performance of the steel shell engine bonding interface under the conditions of damp-heat aging. Two-factor significance analysis can be used to quantitatively evaluate the impact of the pull-off force on the interface. The results show that the mechanical properties of the interface decrease obviously in wet and hot environment, and the humidity change is the main reason.
