Advanced Vibration Solutions,
LLC is a Florida-based consulting engineering company providing comprehensive analyses and objective solutions
to torsional and linear vibration problems in equipment driven by diesel and gasoline engines, electric motors,
and steam turbines.
The potential for vibration problems exists in virtually all rotating
equipment:
Propulsion systems for water-borne craft Dynamometers for analyzing engine performance Diesel generators for primary and peaking electric power Hydraulic pump drives for on- and off-highway vehicles and equipment Cooling tower fan drives HVAC systems
Pumps, fans, compressors, and blowers for industrial and commercial applications
Torsional
vibrations are a silent killer, seldom do they cause a system to vibrate or shake, rather the only indication might
be the failure of a shaft due to fatigue. Other symptoms are gear "hammer," worn gears and splines,
broken crankshafts and bolts, and coupling failures.
Typically, torsional vibration problems are associated with reciprocating piston engines and compressors; however,
due to the range of speeds available with induction motors equipped with variable frequency drives, VFD, torsional natural
frequencies can exist at an operating speed, leading to torsional and/or linear vibration problems of electric motor driven
systems. A torsional vibration analysis, TVA, is an effective method of examining any rotating system for potentially
damaging resonant frequencies and evaluating the appropriate means of detuning.
Mass unbalance, misalignment, loose fits,
resonance, and bearing faults are some of the mechanisms which cause rotating equipment and connected structures to vibrate
and shake. Interpreting the signatures of vibration measurements taken on a system is fundamental to diagnosing and
eliminating the source of objectionable vibrations.
