Magistrantūros studijų baigiamajame darbe pateikiami padangų riedėjimo pasipriešinimo, lauko sąlygomis, tyrimo duomenys, esant skirtingiems atraminio paviršiaus tipams (pieva, ražiena, sausas žvyrkelis), įvairioms padangų vertikalioms apkrovoms (nuo 1,4 kN iki 5,9 kN) bei skirtingiems oro slėgiams padangoje (nuo 0,5 bar iki 2,0 bar). Darbo objektas – padangos riedėjimo pasipriešinimo koeficientas, jo reikšmės kitimas, esant skirtingiems padangos, apkrovos, ir atraminio paviršiaus parametrams. Tyrimas atliktas naudojant BELCHINA 7.50L – 16 ФБел – 253 padangą. Darbo metodai: padangos tyrimams atlikti buvo suprojektuotas ir pagamintas mobilus stendas, kuris buvo tvirtinamas prie savaeigės važiuoklės T–16M. Darbo rezultatai. Oro slėgis padangoje ir vertikalios apkrovos dydis turėjo įtakos riedėjimo pasipriešinimo koeficiento reikšmių kaitai, esant skirtingiems atraminiams paviršiams (pievoje, ražienoje, sausame žvyrkelyje). Mažinant padangos slėgį riedėjimo pasipriešinimo jėga yra tiesiogiai proporcinga vertikalios apkrovos jėgai ir atvirkščiai proporcinga slėgiui padangoje. Pievoje mažiausia riedėjimo pasipriešinimo jėgos Fp reikšmė gauta esant 1,0 bar slėgiui ir padangą apkrovus 1,4 kN vertikalia apkrova (Fp = 14,375 kN). Ražienoje – esant 0,5 bar slėgiui padangoje, ir 1,4 kN vertikaliai apkrovai (Fp = 22,283 kN). Bandymą atliekant ant žvyrkelio – minimali riedėjimo pasipriešinimo jėgos Fp reikšmė buvo tada, kai padangą veikė 1,4 kN vertikali apkrova ir oro slėgis padangoje... [toliau žr. visą tekstą]

The Master’s thesis presents findings of the study of tire rolling resistance under field conditions with different types of support surfaces (grassland, stubble, dry gravel-road), different vertical loads of tires (from 1.4 kN to 5.9 kN) and different air pressures in a tire (from 0.5 bar to 2.0 bar). Object of the thesis – tire rolling resistance coefficient f, change of its values with different parameters of a tire, load and support surface. The study was carried out using the tire BELCHINA 7.50L – 16 ФБел – 253. Methods of the thesis: in order to carry out the tire study, mobile stand was designed and manufactured and attached to self-propelled chassis T – 16M. Results of the thesis. Air pressure in the tire and the value of vertical load influenced the change of rolling resistance coefficient with different support surfaces (grassland, stubble, dry gravel-road). At the tire pressure being decreased, the rolling resistance force was directly proportional to the force of vertical load and is inversely proportional to pressure in the tire. The lowest value of rolling resistance force Fp on grassland was obtained at the pressure of 1,0 bar and vertical load of 1,4 kN on the tire (Fp = 14,375 kN). On stubble – at the pressure of 0,5 bar in the tire and vertical load of 1,4 kN (Fp = 22,283 kN). When the test was performed on dry gravel-road, the minimal value of rolling resistance force Fp was when the tire was affected by vertical load of 1,4 kN and air pressure in the tire...

▼ Currently in US, more than 26 percent of the total GHG emissions comes from transportation and mostly from heavy duty vehicles. Similarly, the European Council stated that 25 percent of the emissions comes from heavy duty transportation and they expect it to be further increased in the future. However, with the new coming regulations US EPA and European Council aiming to reduce the emissions by 80 percent in US and 60 percent in EU. In order to keep track and control the emissions, both authorities published new regulations and testing methods for certifying the new vehicles. Aerodynamic testing is one of the most important part of certification since, aerodynamic drag is a major contributor of total road load acting on a vehicle which is highly related with emissions of a vehicle. Besides, simulation tools for certification such as “Vehicle Energy Consumption Calculation Tool (VECTO)” and “Greenhouse Gas Emission Model (GEM)” needs drag area ( ) as an input. Moreover, it is essential to determine the drag area correctly, therefore, emission of a vehicle, to be able to estimate the amount of total emissions from heavy duty vehicles. Two different regulatory testing methods were published by US EPA and European Council to determine the drag area ( ) for certification of heavy duty vehicles. While US regulations requires “coast-down (CD)” test, EU regulations requires “constant speed (CST)” test. The objective of this study is to compare these two different regulatory approaches with their different assumptions. In order to be able to make a comparison of these two testing methods, CD and CST performed with same tractor and trailer combination, which is a Class 8 truck for US market, in same conditions. Results yielded up to 9 percent difference between two methods. Possible cause of this difference can be listed as, the different assumptions of each testing method such as speed dependency of losses, different approaches for tire rolling resistance and some neglected or unaccounted loses. These possible reasons were also investigated individually in this study. Advisors/Committee Members: Arvind Thiruvengadam, Marc C. Besch, Marc C. Besch.
