Summary:

Auto racing has been in vogue from the time automobiles werefirst built. With the dawn of modern cars came higher enginecapacities; the speeds involved in these races and crashesincreased as well. However, the advent of passive restraint systemssuch as the helmet, HANS (Head and Neck Support device),multi-point harness system, roll cage, side and frontal crushzones, racing seats, fire retardant suits, and soft-walltechnology, have greatly improved the survivability of the driversin high-speed racing crashes.Three left lateral crashes from Begeman and Melvin (2002), Case#LAS12, #IND14 and #99TX were used as inputs to the Wayne StateHuman Body Model (WSHBM) in a simulated racing buck. Twelvesimulations with delta-v, six-point harness and shoulder pad asdesign variables were analyzed for the average maximum principalstrain (AMPS) in the aorta. The average AMPS for the high-speedcrashes were 0.1551±0.0172 while the average maximum pressure was110.50±4.25 kPa. The average AMPS reported was significantly lessthan those reported in real-world accident reconstructions Belwadiet al., 2011 and Siegel and others, 2010, bi-axial material testing(Shah and others, 2006), and in whole body cadavers impacts (Hardy etal., 2008). The seat and shoulder support pads plays a crucial rolein injury mitigation to the thorax in high-speed racingcrashes
