Test Photos:Impact attenuator before, during and after the crush test.Showing maximum deflection of anti-intrusion plate less than one inch.Design Selection:One of the main design goals for this year’s FSAE car was to make many of the componentslighter and more effective than the previous year’s designs. This includes the impactattenuator, where the weight has been reduced by more than 20% and the space occupiedhas been reduced by more than 60%. This reduction in size also allows more flexibility in thedesign of the nose cone. In addition to being lighter and smaller, this year’s impactattenuator absorbed more energy than last year’s, ultimately making the car safer whilestaying within the parameters required by FSAE rules and regulations.
