Aug 09, 2016· In order for this kind of statement to have any merit, the vibration amplitude caused by a known unbalance or misalignment on that machine must be known. Since the transfer function is a frequency dependent ratio of input to output, it is possible to know that there is more force at a given frequency than there was previously.

More ### How is machine vibration defined: Frequency and what else?

Oct 08, 2019· Vibration amplitude. Amplitude defines the magnitude of the machine’s oscillation and is used to judge the severity of the vibration. Oscillations with large amplitude indicate that the vibratory movements are large, fast, or forceful, resulting in more stress
