1 pm to 2:00 pm – Track 2: Durability – Stress, Fatigue Life, SN-Curves, Rainflow, Strain Gauges – John Hiatt 

The durability performance of a product is mandatory: warranty costs must be minimized, and customer satisfaction is paramount.  Overview the complete durability engineering process: 

  • Cyclic Fatigue Principals: Stress, strain, SN Curves, rainflow counting 
  • Gathering load data and calculating damage 
  • Fatigue Life: Miner’s Rule, Stress Life, Strain Life  

1 pm to 2:00 pm – Track 3: Vibration Control –  Introduction, Selfcheck, Random Control – William Flynn 

Success vibration testing requires an intimate knowledge of shaker, control modes, and more: 

  • What is vibration control testing?  
  • Selfcheck 
  • Random Control: Averages per Loop, Weighting, DOFs  

1 pm to 2:00 pm – Track 4: Modal Correlation - Resonance, FRFs, Impacts, Damping – Scott Beebe and Keith Moss 

Avoiding resonances reduces and vibration and increases customer satisfaction.  Learn how to determine the resonances of a structure experimental and calibrate forward looking simulation models: 

  • Natural Frequencies, Damping, Mode Shapes 
  • Frequency Response Functions 
  • Experimental Modal Data Acquisition: Impact Testing 
  • Modal Curvefitting
