| 摘 要： | 利用在同一平面内互相垂直布置的两个非接触式位移传感器，对某精密转轴轴心回转误差运动轨迹进行了测量；再分别用傅立叶变换和相关系数对该转轴的运动特性进行分析，指出在某些情况下，可利用分数布朗运动的相关理论对转轴进行故障诊断，并说明了其适用条件。该研究为回转类机械的故障诊断提出了新的研究方向。

| Abstract: | Measure axis's rotating motion by using two no-contact displacement sensors, which were disposed perpendicularly. Then the sampling data were analyzed by FFT and inter-correlation method. The results indicate when the coefficient of inter-correlation is a smaller value, a new method based on fractional theory can be introduced in analyzing axis radial rotating error motion. |
| |
| Keywords: | fast fourier transform coefficient of inter-correlation radial rotating error variance |
