FSAE赛车吸能器试验研究
Crash Testing of Impact Attenuator for FSAE Car
Abstract
为了满足fSAE2009赛事规则要求,必须为赛车设计合适的吸能器.由于蜂窝铝是一种优良的高强度、吸能性强的轻质材料,XMuT 2009方程式赛车采用蜂窝铝芯作为碰撞吸能器.通过赛车正面碰撞试验对碰撞加速度和动能吸收进行研究,表明XMuT 2009方程式赛车装备的吸能器符合赛事规则要求,将在碰撞过程中为赛车手提供有效保护. To meet the requirement of Formula Society of Automotive Engineers(FSAE)2009 Rules,it is necessary to design an effective impact attenuator.Aluminum honeycomb construction has the advantage of high strength,highly impact resistance and low density.An aluminum honeycomb construction was adopted as the impact attenuator of Xiamen University of Technology(XMUT)FSAE racing car 2009.The crash testing was carried out for a frontal impact.Deceleration and the energy absorbed were studied.The impact attenuator attached to the front of XMUT FSAE racing car 2009 complies with the rules.It absorbs enough kinetic energy and provide protection in the event of a collision.
