Vibration Analysis (VA) is a key technique used for maintenance and fault detec­ tion of vibrating machinery. The purpose of maintenance is to analyze how well the machinery is operating within its target parameters, while fault detection is done to diagnose and locate a fault that might be developing on the machinery.
