Thermal and Vibration durability test cell

The purpose of this equipment is  to analyze and stress in both thermal and vibration strengths on board components for passenger cars and commercial vehicle application.

The bench is particularly adapted to durability testing following strict technical specifications on the behalf of OEMs and car manufacturers and especially :

  • Turbochargers and exhaust parts testing (using both shaker and gas burner)

  • Mechatronics, electric, electronic and plastic parts testing (using both shaker and thermal cell)
