Figure 6

Relation of ESS moving speeds and brain injury indices of ESS riders under the impact speed of 10 m/s.

(a) Relation of ESS moving speeds and brain injury indices (coup pressure and contrecoup pressure) of a doublewheel ESS rider with an impact speed of 10 m/s

(b) Relation of ESS moving speeds and brain injury indices (von Mises stress and shear stress) of a doublewheel ESS rider with an impact speed of 10 m/s

(c) Relation of ESS moving speeds and brain injury indices (coup pressure and contrecoup pressure) of a solowheel ESS rider with an impact speed of 10 m/s

(d) Relation of ESS moving speeds and brain injury indices (von Mises stress and shear stress) of a solowheel ESS rider with an impact speed of 10 m/s
