| 为了实现通过改变压气机机匣材料、结构形式和加工手段，达到减轻压气机机匣质量的目标，依照骨架式结构设计思
想，对某型压气机的机匣进行了骨架式结构的改进设计，即“桁架”式结构机匣，并针对这3 种典型的结构机匣分别从静强度、模态
和包容特性等角度进行了仿真计算和对比分析，得到了现阶段最优方案为圆形开孔机匣。结果表明：该类骨架结构可以实现在不影
响机匣使用要求的前提下，将压气机机匣质量减轻10%~20%，有效提高发动机推重比。 |

| In order to reduce the compressor casing weight by changing the casing material, structure form and manufacturing method,
according to the principle of the skeletal supporting frame structure, the improved design of skeletal supporting frame structure for a
compressor casing was conducted, which was truss structure. The simulation and comparative analysis of three kinds of typical structure
casing were performed respectively from the static stress, mode and containment capability, and the best scheme was obtained at present
that was circular opening casing. The result shows that the skeletal supporting frame should reduce the compressor weight as 10%~20% to
improve the engine thrust-weight ratio, which has no influence on casing application requirement. |
