Machinery vibration diagnostics

Vibration is a process that can not be measured, unlike its parameters. The machine can have high levels of vibration for three reasons: – there is a strong source of vibration inside the machine; – during spreading between source of vibration and the point of observation, vibration weakly damped or even increases due to good conductivity and transparency of the surrounding structures; – there are two previous reasons simultaneously. For solving the first problem we have to explore the physical nature of vibration inside the machine. For solving the second problem it's necessary to investigate the spread of vibrations out of the construction.
