vibration spectrum मीनिंग इन हिंदी

A single point vibration spectrum does not provide good and reliable indication of machinery misalignment.
Many units display the full vibration spectrum of three axes simultaneously, providing a snapshot of what is going on with a particular machine.
VA can use the units of Displacement, Velocity and Acceleration displayed as a Time Waveform ( TWF ), but most commonly the spectrum is used, derived from a Fast Fourier Transform of the TWF . The vibration spectrum provides important frequency information that can pinpoint the faulty component.
