Furthermore, the stability of rotor shaft system in centrifugal compressor with largely supported span is analyzed in example and the optimized design scheme for rotor shaft system is pointed out.
举例对大支撑跨距离心压缩机的转子轴系进行稳定性分析，并提出对转子轴系进行优化的设计方案。

On the basis of wavelet packet decomposition technique introduced firstly, the measured unstable oil-film oscillations of single-disc and single-spanrotor system were investigated.
The efficiency distribution along blade span and the inlet and outlet velocity triangle measurement of rotor blades were made around the designing point.
