摘要:
叶轮是航空发动机的重要组成部分，需要具有高的加工精度和质量。以某机床厂生产的航空发动机叶轮专用加工中心X轴滑座为研究对象，采用有限元方法分析其动态特性。根据其固有频率和模态振型找出X轴滑座结构的薄弱环节，针对X轴滑座的薄弱环节提出优化设计方案，以提高X轴滑座的动态性能，为以后的设计提供了一定的参考。
Impeller as an important part of the Aero-Engine should have a high machining accuracy and quality. The X-axis slide of Aero-Engine impeller dedicated machining center is taken as the re-search object, which was turned out by a machine tool factory, and its dynamic characteristics are studied by finite element analysis. The weaker part of the X-axis slide is founded according to the analysis of inherent frequency and modal shape, and as to the weaker part, optimization design scheme is put forward to improve the dynamic characteristics of the X-axis slide. This conclusion provides a certain reference to the future optimized design.
