摘　　要：为了验证航空发动机机匣包容性破坏势能法,本文完成了20次模型机匣包容性冲击试验,得到了模型叶片撞击模型机匣时的速度、应变响应和模型叶片撞击模型机匣过程的高速摄影照片。试验结果表明,该模型机匣的非包容失效模式主要是剪切破坏。本文还采用数值分析方法对机匣包容性进行了模拟,计算结果与试验结果吻合良好。In order to validate destroy potential energy method of casing containment, 20 impact tests have been completed. The speeds of model blade, and strain responses of model casing were reported. At the same time, the process of model blade impacting model casing was recorded continuously by high-speed photography. The results indicated that model casing was destroyed by shear stress. The containment of casing was calculated through numerical analysis method. The results of numerical analysis were identical with experimental results.
