ABSTRACT:
One embodiment of the present invention provides a system that generates a vibration profile for a rotational device in a computer system. During operation, the system sequentially sweeps a rotation speed of a rotational device over a range of rotation speeds. While driving the rotational device at each rotation speed, the system collects a time-domain vibration signal produced by the rotational device and subsequently computes a frequency spectrum of the time-domain vibration signal. In this way, the system generates a set of frequency spectra associated with the range of rotation speeds. Next, the system combines the set of frequency spectra to generate a composite vibration profile for the rotational device.
