Programmable Stopping Device Design for Sled Test

Full vehicle crash testing is used to reproduce the dynamic conditions of real world car accidents. The complex and destructive nature of these crash tests make them very expensive. For these situations, sled testing becomes preferred evaluation for occupant injury. Sled test is simulated crash test facility used to test components like seats, seat belts, child restraint systems, seat anchorages on body shell etc. the crash condition is simulated and the components are subjected to these conditions. The crash condition includes the velocity of crash and the deceleration level at the time of crash. There are number of international standards such as ECE regulations (Europe), FMVSS (USA) and ARAI testing standards (India) etc, which specify the conditions and limits for various parameter for above mentioned tests.
