Effect of inflation pressure on motion resistance ratio of a high-lug agricultural tyre

Multi-criteria optimization model to investigate the energy waste of off-road vehicles utilizing soil bin facility

“…7 also suggests that increase of tire inflation pressure brings about the reduction of energy waste in contradictory to wheel load effect which is previously discussed. This could be attributed to the ballooning effect of overinflated tire which reduces tire deflection and thus decrease of rolling resistance as reported in literature [5,9]. Finally, the interaction effect of velocity and inflation pressure is observed in 3D curve and contour plot of Fig.…”

Relationships among the contact patch length and width, the tire deflection and the rolling resistance of a free-running wheel in a soil bin facility

“…Many studies have been designed so far to measure experimentally the rolling resistance focusing on the effect of different variables such as wheel load, tire inflation pressure, speed, sinkage, etc. on rolling resistance (Çarman, 2002;Zoz & Grisso, 2003;Way & Kishimoto, 2004;Elwaleed et al, 2006;Coutermarsh, 2007;Kurjenluoma et al, 2009;Taghavifar & Mardani, 2013). Analytical models have also been developed for determination of rolling resistance (Bekker, 1960;Pope, 1971;Wong, 1984;Komandi, 1999).…”

“…low inflation pressure (not with road pressure, high inflation pressure) in soft soil. Elwaleed et al (2006) explored the effect of tire inflation pressure on lugged tires using a single wheel-tester and reported that reduced inflation pressure led to the decrease of rolling resistance; however, more decrease than recommended value resulted in the increase of rolling resistance. Çarman (2002) also reported that rolling resistance has a polynomial increase with the increase of wheel load.…”

Energy loss optimization of run-off-road wheels applying imperialist competitive algorithm

“…Investigations propose that almost 20-55% of the energy developed to the drive tractor wheels is wasted in the tire-soil interaction [1]. This energy is not only wasted, however, the follow-on soil compaction produced by a portion of this energy may be damaging to crop yielding [2].…”

“…Dissipated fuel due to mismanagement in the domain of agricultural tires was reported to be about 575 million liters per year in USA [4]. So far, many attempts have been conducted to predict rolling resistance theoretically [5][6][7][8][9] and empirically [1,[10][11][12][13], amongst which the joint intention was rolling resistance prediction through various modeling approaches. However, population-based evolutionary optimization assessments are required for minimization of energy waste due to rolling resistance.…”
