| 中文摘要: |
| 通过建立某航空发动机整体叶盘的三维实体模型，针对整体叶盘结构的耦合振动特性进行了固有模态特性分析。根据有限元软件ANSYS的计算结果，绘制了叶片共振转速Campbell图，分析了整体叶盘结构模态振动的基本特性，得到了整体叶盘节径-频率图，分析的结果为进一步研究整体叶盘的结构设计优化和避免共振提供了依据。 |
| 英文摘要: |
| A 3-D entity model of aero-engine holistic bladed disk is established and the natural model of vibration is analysed to the coupling vibration characteristics. According to the calculations of the FEA software of ANSYS, we get the resonance speed Campbell figure of the blade, analyse the basic characteristics of structure model vibration and get the pitch-frequency figure of holistic bladed disk. The results supply the reliable assurance for further studies on the structure optimization design and avoidance of resonating of the bladed disk. |
