Compact servo-hydraulic sled system

  • 10-Jan-2013 05:17 EST

MESSRING Systembau’s compact impact simulator (CIS) is designed to test vehicle components, such as safety belts, airbags, seats, or roof carriers, effectively, precisely, and reproducibly within a relatively small floor space without requiring a complete crash test facility. The system uses a servo valve and a hydraulically powered ram to accelerate a test sled to speeds of up to 65 km/h (40 mph). The sled is guided in a track system and features controlled braking by a wear-free brake. The overall system operates fully automatically and can be independently controlled by just one person. The CIS can be used to smoothly perform many different standardized tests. Additionally, the CIS integrates the M=BUS data acquisition system; this measuring module is mounted directly to the acceleration sled and routes highly precise results to the control software for evaluation.
