Abstract:
Since their introduction into NASCARĀ® (National Association for Stock Car Auto Racing, Inc.) in the early 1950s roll bars have played a vital role in protecting race car drivers from injury during crashes. Just as helmets, seats, seatbelts and a multitude of other safety enhancements have evolved and transformed racing safety, so too have roll bars. From serving as additional bracing in early stock cars, to being the primary chassis and frame system in modern NASCAR vehicles, tubular roll bars have changed dramatically.This paper summarizes extensive quasi-static testing of tubular joints. Test variables included joining method and gusset design. Also described are the material properties, engineering characteristics and joining methods currently used in modern NASCAR vehicle chassis fabrication.
