Automotive Vibration Testing

Vibration testing plays an important role during vehicle development, and often times testing continues throughout production. Vibration testing allows engineers to characterize the effect of long-term, road-induced vibration and shock on the performance and service life of automotive systems, sub-systems and vehicle/engine components.

UD shaker systems perform these environmental tests, with the intent to qualify the vibration durability of the part under test or identify design deficiencies that must be corrected.

Typical parts tested using UD vibration shakers include:

  • Alternators and Starters
  • Exhaust Gas Recirculation (EGR) Valves
  • Fuel rails
  • Air bag sensors and hardware
  • Throttle bodies
  • CV Transmissions
  • Instrument panels
  • Consoles
  • Engine control units
  • EV Batteries
  • Exhaust systems and Catalytic converters
  • Inverters
