Abstract:
Objective To explore the effectiveness of the protective emergency ambulance chassis against damage from explosive weapons such as grenades and mines.Methods A 12 mm-thick polyethylene(PE)protective plate and a composite ceramic PE protective plate(1 mm-thick aluminum plate+6 mm-thick B4C ceramic+12 mm-thick high molecular weight polyethylene fiber)were involved in for the protection of the chassis of an emergency ambulance under the premise of meeting the ambulance's protective requirements.Theoretical calculations and simulations were used to analyze the blast damage effects of a 62 g TNT grenade on the PE protective plate and a 6 000 g TNT equivalent mine on the composite ceramic PE protective plate.Results The PE protective plate and composite ceramic PE protective plate were able to withstand the destructive effects of a grenade and a mine at a blast distance of 1.1 m,respectively,and no significant damage was observed in either case.Conclusion The PE protective plate and composite ceramic PE protective plate meet the requirements for mobility,lightweight and protection against damage from explosive weapons such as grenades and mines,and references are provided for designing protection schemes of the protective emergency ambulance chassis.[Chinese Medical Equipment Journal,2024,45(6):23-27]
