Development of modular vibration test rig with machine fault testing and analysis

Vibration monitoring is one of the most common and widely used fault monitoring methods in industries to estimate components fault occurrence in machineries. Vibration test rigs which were used to conduct various studies on vibration monitoring are commonly single functioned. They are focused on con...
