EVALUATION OF THE OPERATIONAL PROPERTIES OF AN ALL-TERRAIN VEHICLE POWERED BY HYDROGEN

The paper considers the reasons for the creation of an all-terrain vehicle powered by hydrogen, using a fuel cell electric power generator as a power unit. The design of the RUSAK K-8 FCEV all-terrain vehicle, characteristics of traction electric motors, traction batteries and inverters are presented. The features of calculating the indicators of traction and speed properties of vehicles running on hydrogen are considered. The introduction of overload coefficients for current and voltage is proposed. The results of calculations of acceleration time and path indicators, indicators of the maximum 30-minute driving speed with and without the entered coefficients are presented. A comparative analysis of the obtained results is carried out. It is proposed to use the parameter of the 30-minute maximum speed as a criterion for choosing the energy intensity of traction batteries or the volumes of hydrogen cylinders.
