Development of Evaluation Technique for Occupant Safety in KHST by Sled Test

This paper uses a dynamic sled test approach to understand the effects of impact speed on the risk of occupant in KHST. The sled impact tests simulate a predefined accident scenarios. This study shows the effect of relative velocity between occupant and struck vehicle while occupant is impacted to a front seat's seatback. Although, base on the current accident scenarios, KHST is performed well enough to protect average adult male occupants. However, Results from the tests indicate small size occupant or higher impact speed may cause sever neck and femur injuries.
