Using of the Trucks with Electrical Drive on the Farm Enterprises

Abstract

A problem of using of the electric drive trucks on the farm enterprises was investigated in present research work. According to the results of the litera-ture sources analysis there was found a great interest of scientists and users concerning the usage of the commercial electric vehicles in the agriculture. There was made a mathematical modeling of the power consumptions by trucks of gross weight 4000, 8000, 10000 and 12000 kg taking into account their different operating conditions, a movement by an asphalt concrete, road-metal, ground pavement. There was determined that a vehicle move-ment on a pavement with a high value of rolling resistance coefficient leads to an abrupt increasing of the power consumption, up to 2…2,5 times. There was made a comparison of the values of received power consumptions with the results that were received by another scientists using another research methods. A deviation of received results of the specific power consumptions consists within 5…20 %, that is accessible and says about their sufficient convergence. A perspective of further investigations should be directed to a possibility of quick replenishment of the power supply, a determination of rational correlation between different power sources, and to a receiving of detailed characteristics of the vehicles operating conditions that are used in the agriculture.
