Advanced Vibration Solutions, LLC

Specializing in "detuning" systems . . . preventing and eliminating damaging torsional and objectionable linear vibrations in rotating equipment.

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

Gear "hammer," worn gears and splines, broken bolts and shafts, and coupling failures are some of the signs of a torsional vibration problem in a system. 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 vibratory responses 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.
