Motorcycle helmets are essential for reducing the risk of head injuries in the event of an impact.However, during the design of helmets, a compromise must be made between user safety and user comfort.Accordingly, the present merlin wizard costume study proposes a novel open-face helmet design, in which the helmet features three ventilation slots in the upper-head region.

Finite element analysis (FEA) models were constructed for both a prototype helmet design, and three traditional helmet designs (full-face, open-face, and half-face helmets).In simulating the proposed open-face helmet, this study considered three different ventilation slot widths, namely 8, 14, and 18 mm.The simulation results showed that of all cartoon martian with big head the helmet designs, the half-face helmet resulted in the greatest headform acceleration (303 G).

The internal ventilation helmet achieved a lower peak acceleration than that of the full-face helmet.By contrast, the proposed open-face helmet with ventilation slots resulted in the lowest acceleration, irrespective of the ventilation slot width.The 8-mm ventilation slot width resulted in the optimal impact performance level (i.

e., a peak headform acceleration of 160 G).Overall, the results suggest that the proposed open-face helmet design with ventilation slots provides a promising solution for ensuring both user protection and user comfort in warm climates.
