高速旋转轴系的扭振模态实验研究

his paper is mainly about the torsional measurement of the rotating shaft at different speed using the ATI 2000 series torsional measurement system. It is based on the high speed rotating mechanism of Wuhan University of Technology. Through the data analysis and the post processing, We manage to get the first natural frequency of the output shaft. After the comparison between the Ansys simulation result and the experiment data，the reliability of the system has been proved. Besides, the noise reduction based on the wavelet is apparently useful and helpful, making the foundation for the further model analysis of the whole rotating system.
