摘要

基于气动轴承与轴系耦合调频技术

对高速压气机涡轮转子结构的空气循环制冷机轴系进行非线性振动性能的试验研究

进一步分析了柔性轴系存在转子运动、轴承失稳及碰摩故障的一些非线性特征.研究结果表明:在保证转速设计裕度的前提下

工作转速由40000r/m提高到了60000r/m.

Abstract

Based on gas-dynamic bearings and frequency coupled modulation of rotor-bearing system

the characteristics of rotor bearing system's nonlinear vibration experimental investigations were applied to high-speed air cycle refrigerator.Furthermore

some nonlinear characteristics

for example

the motion of rotor

bearings instability and rub-impact which always happen on the flexible shaft

were analyzed.The results show that

if the design margin of safe speed is guaranteed

the steady running speed of the rotor-bearings system can be effectively increased from 40000r/min to 60000r/min above.
