Harness Durability Testing

Customer Need / Challenge

  • Harnesses are often used to strap humans of various weights to safety equipment or sports gear.
  • Harness manufacturers must determine load and durability factors for harnesses and their attachment points.

 

Interface Solution

  • A drop test apparatus uses an Interface Model 1200 Load Cell attached to a cable and loaded harness.
  • The Loaded harness is dropped from a specified height to measure the force generated during sudden stop at maximum cable extension.

 

 

 

Results

  • Engineers determine the total force on the harness for various body weights dropped from maximum usage heights to set harness limits.
  • Tests can be repeated numerous times to determine fatigue and durability limits.

 

See how this was accomplished using an Interface Model 1200 Standard Precision LowProfile™ Load Cell attached to a cable and loaded harness, and an INF-USB2 Universal Serial Bus Signle Channel PC Interface Module.
