对于回转运动来说,即使最微小的形状误差也会限制计算机磁盘驱动器的准度。其中最主要的故障原因是径向跳动。典型的例子是利用示波器来记录跳动值,但它仅能给出数值大小。另一种方法是利用频谱分析仪,它不仅能给出跳动值,还能给出频率值,以帮助我们诊断径向跳动的原因。 For slewing motion, even the smallest form-factor errors limit the accuracy of your computer’s disk drives. One of the most important causes of failure is radial runout. A typical example is the use of oscilloscopes to record jitter values, but it can only give values. Another approach is to use a spectrum analyzer that not only gives the beat value but also gives the frequency value to help us diagnose the cause of the radial runout.
