Structure and Machine Natural Frequency – INDOAERO

The pipes,foundation, and rotating machinery in every plant have natural frequencies. If designed well, the natural frequencies are not excited (much). However, if a machine happened to be mounted on a structure that had a natural frequency equal to speed of the motor, the vibration level would grow considerably-there would be a resonance.
