Wire Bending Deceleration Sled

The use of sled testing is desirable when looking to run multiple non-destructive tests where the acceleration environment is already defined. It is a repeatable and cost effective method to reproduce the dynamic condition of full-scale crash tests as well as component testing in a controlled environment. Exponent’s indoor sled facility utilizes a Seattle Safety wire-bending deceleration sled that is powered by a pneumatic acceleration system and capable of generating up to a 35 g peak deceleration or a deceleration profile over 60-inches of displacement. The wire-bending decelerator is capable of sustaining a maximum load of 175,000 lbs. A 170-ft approach rail minimizes test article disturbance during the acceleration phase allowing the sled to reach a maximum speed of 40 mph. Pre-impact braking technology allows for up to 50 feet of low-level deceleration prior to impact. Similar technology has been applied to our outdoor roller coaster dolly. The indoor sled facilities have 200kw of lighting that allows for high-definition high-speed and real-time video.
