Bobcat Company: Vibration Fatigue Analysis of a Cooling Fan Mount

A cooling fan mount was failing during the field validation process despite high measured fatigue life values. The ultimate root cause was high residual stress from the assembly procedure. This presentation illustrates Bobcat's integration of nCode GlyphWorks and nCode DesignLife. nCode GlyphWorks was used to process the field data to extract two possible load cases. nCode DesignLife was used to identify the more probably load case and also shows the effects of the mean stress. nCode DesignLife was used to help set up a lab vibration test to validate the new design. Results from nCode DesignLife and nCode GlyphWorks were compared with the fatigue failures produced by the lab test. Presenter: Patrick Stahl, Bobcat Company
