Electrical Cable Reels - Failure Analysis - Fatigue
Mechanical FEA was used to examine take-up reels used in the manufacture of communications and electrical cable. Computer modeling of static and dynamic loads due to centrifugal loading about multiple axes was critical to understanding the stresses exerted on the reel during factory operation. Stress and deformation was used to evaluate member size, welded connections and susceptibility to long-term fatigue. Vibration modes were also examined to determine resonance potential.
