Résumé

High vibration in reciprocating machinery is a common occurrence. Vibration produces alternating stresses in the material. Alternating stress levels beyond the endurance limit of the material causes fatigue failure. Failures of this type can be catastrophic. Consequently, measures are taken to avoid high vibration. Vibrations can usually be attributed to either the mechanical or acoustical design. One key to controlling vibration is the understanding and manipulation of each systems' unique acoustical characteristics
