拉杆数目和轮盘级数对组合转子性能退化的影响规律

The Influence of Rod Number and Disc Series on the Performance Degradation law of Combined Rotor

本文主要从几个不同方面对由差异数量下的拉杆数目、以及内部组合部分的轮盘级数所共同组建的转子性能进而对其产生的退化特性以及基于原始数据下的组合转子对同一位置出现不同初始尺寸裂纹、同一尺寸裂纹出现在每一个不同的地方使得拉杆不在各个位置都极其敏感。最后得出一些列有关拉杆数和每一级轮盘数在一定程度下对组合转子随时间变化产生的退化影响分析,还包括由于使用不当或者疲劳应力最终导致拉杆裂也会直接性产生部分影响,本次研究不仅为组合转子的性能退化提供了规律研究同时也对一定理论参考价值具备相应的指导意义。

The paper mainly studies the effect of rod number,disk stage on dynamic performance degradation mechanism,and the sensitivity of combined rotor degradation due to the crack on rods the position and initial size.The results show the influence of rod number and disc series on the degradation law of combined rotor,and the degradation law of combined rotor due to rod crack position,which provides a certain theoretical reference value and guiding significance for the study of performance degradation law of combined rotor.
