Spectral vibration analysis is a critical tool for ensuring that the different pieces of equipment on board a rail vehicle are in proper working order.

The main applications for spectral vibration analysis include:

• Evaluating the balance of ceiling-mounted resistance fans.
• Evaluating the status of electric traction engine rollers.
• Evaluating the efficacy of fan motor couplings in air conditioning equipment.
