Математическая модель расхода топлива форвардера «амкодор-2682» при выполнении лесохозяйственных работ

Abstract

Cost justification of fuel and lubricants is high on the agenda of planning and practical use of forwarders in Russia and abroad. The problem solution is becoming increasingly important due to rising prices for fuel and energy resources. The share of costs for fuel resources ranges from 46 to 70 % in different natural and industrial conditions. This is due to the presence of cutting areas with different characteristics of the species composition. Currently, there are consumption rates for fuel and lubricants for mechanized work performed in forestry. However, they lack regulatory guidelines for calculating the fuel of modern logging machines used in skidding. There are basic standards for consumption of fuel, oil, and lubricants for different brands of domestic and foreign cars, trucks, and buses, but they also have no information on forestry equipment. The research purpose was to show the fuel consumption for the forwarder Amkodor-2682 when harvesting assortments in the climatic conditions of the Mari El Republic. The purpose was achieved through experiment using the volumetric method of refilling the machine fuel tank at the end of the operation cycle. The studies were provided with fixing the diameters and volumes of the felled trees. The forwarder fuel tank was filled to the top of the tank filler. Processing of the swath site was carried out with skidding of one pack of logs. The machine was stopped and the fuel tank was filled in after each operation of logging (idling, bundle assembling, hauling, bundle unloading). The amount of fuel in the tank was accurately fixed each time. Processing the data allowed us to obtain a regression model. This model characterizes the average fuel consumption for the forwarder Amkodor-2682 at different diameters of felled trees. Using the obtained results in forestry will make it easier to plan and calculate the operating costs of skidding equipment.
