Abstract

In road and off-road motorcycle accidents, neck injury often has a catastrophic outcome if not fatal. To protect motorcyclists’ necks, a number of neck–braces are available on the market. The level of protection from these systems is not well reported because of the absence of an accepted neck-loading evaluation standard. The present study proposed a numerical evaluation for the neck–brace to protect the neck. Twenty-four impacts with and without the brace were simulated by changing impact angles and initial impact velocities. For each simulation, the vertical force, the extension moment, and the normalized neck injury criterion were calculated. Results showed that the risk of AIS 3 + neck injury was reduced by the neck–brace on average by 39 and 13% at 5.5 and 6.5 m/s, respectively, when the normalized neck injury criterion was considered; however, for impact velocities, above 6.5 m/s, the neck–brace was not as efficient in reducing overall neck injury risk.
