| 中文摘要: |
| 为了解决试验器条件下航空发动机轮盘爆裂产生的能量问题，采用包容曲线法、破坏势能法、2 阶段能量法及数值仿真
法进行立式转子试验设备包容壳体的厚度设计。计算结果表明：轮盘爆裂后最大碎块为1/3 轮盘碎块，并且碎块最大平动动能明显
高于平均平动动能；依据已有的试验结果，对得出的结果进行安全性评定；采用2 阶段能量法计算得到的结果与试验结果的符合性
较好，仿真分析需要准确的失效应变数据以得到可靠结果，最终使用2 阶段能量法以3 倍安全系数确定包容壳体的厚度应不小于0.2 m |

| In order to solve the energy problem of the aeroengine disk under the spin test condition，the design of the containment
shell thickness of the vertical spin test facility was carried out by the containment curve method，the failure potential method，the 2 stage
energy method and the numerical simulation method. The calculated results show that the largest fragment after burst was 1/3 disk debris，
and the maximum translational kinetic energy of the fragment is obviously higher than the average translational kinetic energy. According to
the existing test results，the safety of the obtained results are evaluated. The results obtained by the 2 phase energy method are in good
agreement with the test results. Accurate failure strain data is needed for the simulation analysis to get reliable results. Finally，the thickness
of the containment shell is determined with 3 times the safety factor using the 2 phase energy method. The thickness of the containment
shell should be less than 0.2 m. |
