## A Brief Tutorial on Machine Vibration

2016-2-23  vibrations on machines are corrected by mass balancing, aligning, or changing the bad parts. Natural vibrations are a structural effect, where some structure behaves like a mechanical amplifier that is frequency sensitive. The symptoms of natural vibrations, or resonance, are: 1. The vibration is very bad, in other words, abnormally high amplitude. 2.

Also, the vibrations tend to be localized, and the associated displacements depend on the position and the structural configuration. Moreover, the finite length of the machine parts influences the propagation of the mechanical waves along the structure. The reflections at both ends interfere along the actuator structure, forming a stationary wave.
