Abstract
International standards ensure that equestrian helmets achieve high performance. Recently, one such standard (PAS 015) was revised to include a lateral deformation requirement, ensuring helmets can withstand the potential crushing forces associated with equestrian. This increased performance needs to be achieved against a minimal mass penalty, which is an important consumer consideration. This paper explores how shell design optimisation can improve crush resistance, validated using additive manufacturing and mechanical testing. This approach achieved a 73% increase in crush force, for only an 11% mass increase.
