Vibration acceptance criteria - Maintenance
Vibration EFFECTS. Vibration acceptance criteria By Adam Mayers, mechanical engineer, Aspec Engineering The effects of vibrating loads on structures can often be significantly greater than the effects of static loads of equal or greater magnitude. T hese effects can include, among others, fatigue damage such as cracking and breakage, damage to operating equipment due to excessive ambient Vibration and human discomfort. These guidelines are very useful as a first pass to de- termine the suitability of Vibration levels. Where there are significant structural integrity concerns however, a detailed Traditionally, structures subjected to dynamic loads have Vibration and fatigue analysis, often using finite element been designed by trying to ensure that the major natural fre- methods (FEA), may be required. Again, this analysis should quencies of the structure are not close to the frequency of the consider the full response of the structure to the applied vi- applied forces.
