Event Brief

The purpose of this course is to provide training for sine, sine sweep, random vibration and shock analysis, where the excitation is applied as an input to a dynamic system.   The systems include finite element models of beams, plates and circuit boards, as well as simple spring-mass models.   Rainflow cycle counting and equivalent spectral methods are used to calculate the stress-cycles.  The material S-N curve is identified.  The stress-cycle and fatigue curves values are then fed into a Palmgren-Miner cumulative damage summation.  

Some of the topics are similar to those in Dave Steinberg’s Vibration Analysis for Electronic Equipment.  Furthermore, Steinberg’s electronic component fatigue empirical formula is developed into a complete S-N fatigue curve.

The course also covers methods for calculating the relative damage between two different dynamic environments.  This comparison can be used to determine whether one environment is more severe than another.  It can also for deriving a power spectral density specification to envelop field accelerometer data.
