The frontal impact response of a spaceframe chassis sportscar

The frontal impact behaviour of a low volume, niche market sportscar with a spaceframe chassis has been investigated using the non-linear finite element code Oasys LS-DYNA3D. In considering the options for crashworthiness improvements, it was first essential to understand and have confidence in the overall structural response that was being predicted. An experimental test programme has supported the finite element predictions and has included the impact testing of typical brazed tubular structures and an automotive wheel and tyre. Results from a 23 000 finite element vehicle model correlate well with the digitized results of a crash test video.
