The Fatigue Damage Spectrum and Kurtosis Control - January 31, 2012 @ 5:30pm
(Session 31)

Matt Millard will be presenting at the 2012 SEM IMAC Conference & Exposition on Structural Dynamics in Jacksonville, Florida on January 31st. Matt will present on the "Fatigue Damage Spectrum and Kurtosis Control" in the Sensors & Instrumention division.

Abstract: The accumulated damage that a product experiences in the field due to the variety of stresses placed upon it will eventually cause a failure in the product. These failure modes can be replicated in the laboratory using random vibration testing. During the past several years, the vibration industry has been introduced to Kurtosis Control – a new technique that brings about these failure modes in the laboratory in a more realistic and speedy fashion. The Fatigue Damage Spectrum (FDS) is an effective tool that can show the damage a product will experience at a particular frequency and the effect Kurtosis Control has on the random vibration test. Kurtosis Control is a more effective method than traditional random vibration tests because it brings products to failure more quickly. The Fatigue Damage Spectrum shows the increasing fatigue damage across all frequencies that accompany the increased kurtosis levels that cause the faster product failure. The FDS is another great tool that clearly illustrates the effectiveness of Kurtosis Control. More info...
