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 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 2in1 Acrylic considered three different ventilation slot widths, namely 8, 14, and 18 mm.The simulation results showed that of all 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 Red Root user comfort in warm climates.
