Virtual Instrumentation Based Heavy Machinery Vibration Analysis

Vibration analysis is found to be a significant approach in industries for analyzing the performance of rotating machinery. Vibration is caused due to bearing faults, angular and parallel misalignments, loose joints and improper mounting. Vibration textures vary signal patterns in time and frequency domain and they carrying the impact of certain faults in rotating machinery. The measurement of vibration becomes necessary due to the increasing demand for higher productivity, power consumption, economic design with higher operating speed and assurance for the safety margins. Vibration analysis is further useful in identifying the natural frequencies to avoid resonance and to prevent structural instability.
