THE THEORETICAL SUBSTANTIATION OF THE COMPUTATIONAL ALGORITHM OF FUEL CONSUMPTION BY DUMP TRUCKS

The purpose of article is to determine, design and construct (optimize) algorithm of quantitative and qualitative indicators of efficiency of use and economy of fuel by dump trucks during unloading cycle. The article considers a group of factors on which fuel consumption depends and determines which factors are the priority. An analysis of the existing normative calculation of fuel consumption for dump trucks, which operates in Ukraine at the state level. Also, in the article the fuel consumption is considered depending on the loading characteristic of the car-dumper at different speed of rotation of the crankshaft, change in fuel consumption, depending on the speed and impact on the fuel consumption of the gear ratios in the general form without cargo and with the load, dependence of fuel consumption on the average speed of unloaded and loaded vehicle. An analysis of the main material and methods for calculating fuel consumption by dump trucks was carried out on the basis of which the conclusion was drawn and presented in the article. The object of the study is the change in fuel consumption by dump trucks during unloading at different crankshaft rotational speeds. The study of fuel consumption by dump trucks during the unloading process requires detailed study, since the exact fuel consumption rate for this process has not been determined and studied, therefore the issue of cost, optimization and fuel economy in the unloading cycle is relevant and requires further research.
