“…On the other hand, for evaluation of tyre-pavement interface-related phenomena (most notably tyre/road noise), Von Meier (Von Meier, Van Blokland, & Descornet, 1992) proposes to use MPD modified by the 'enveloping' algorithm that accounts for elastic properties of the tyre tread. Many studies (Cesbron, Anfosso-Lédée, Yin, Duhamel, & Le Houédec, 2008;Ejsmont, Taryma, Ronowski, & Swieczko-Zurek, 2016) indicate that deformations of the tyre tread are very complicated and that energy losses in the rolling tyre depend on inflation pressure and tyre load in a rather complex way, different on various road surfaces (and that supports the hypothesis related to the partial enveloping).…”

Tyre performance, one of the critical factors for vehicle users, is strongly related to the road surface characteristics, most notably to the pavement texture. Phenomena that occur at the tyre/road interface affect tyre friction (skid resistance), rolling resistance, tyre wear and tyre/road noise. This article deals with relationship between surface texture and rolling resistance of light and heavy vehicle tyres. Mean profile depth (MPD) is one of the most common descriptors of road surfaces and in many studies it is correlated with rolling resistance of tyres. Results of measurements performed by the Technical University of Gdańsk show that although the correlation exists, it is not very strong and regression between MPD and rolling resistance is not linear. The key reason for this is partial enveloping of the tyre tread interacting with pavement texture. The article presents results of laboratory and road measurements of rolling resistance performed on road surfaces characterised by MPD from 0.20 up to 4.75 mm and the correlation of the rolling resistance coefficient with MPD. Certain aspects of texture enveloping and influence of this phenomenon on rolling resistance are discussed.

“…But normal load increment has a contradictory influence on slip resistance, since it increases the contact patch length, which together with normal load increase, leads to a reduced slip resistance. Although the rolling resistance coefficient does not remain constant as normal load changes, experiments have shown that normal load change has a minor influence on rolling resistance coefficient in radial tires [10]. Accordingly, the impact of normal load on rolling resistance coefficient has been neglected in the current study.…”

“…As one of the main sources of energy consumption, rolling resistance has been already conducted in detail. Experimental results show that rolling resistance is influenced by several parameters such as tire structure, normal load, inf lation pressure, and road pavement [10]. The ongoing progress for achieving more efficient tires has led to introduce low rolling resistance tires that are claimed to deliver up to 30% reduction in rolling resistance [11].…”

Investigation of vehicle resistant forces and power losses is of crucial importance owing to current state of energy consumption in transport sector. Meanwhile, considerable portion of resistant forces in a ground vehicle is traced back to tires. Pneumatic tires are known to be a source of energy dissipation as a consequence of their viscoelastic nature. The current study aims to provide a modification to tire resistance by considering the power loss in a tire due to longitudinal slip. The modified tire resistance is comprised of rolling resistance and a newly introduced resistance caused by tire slip, called slip resistance. The physical model is chosen for parameters sensitivity study since the tractive force is described in this model via tangible physical parameters, e.g. tire tangential stiffness, coefficient of friction, and contact patch length. Hence, the tire physical model is capable to investigate the influence of different parameters such as coefficient of friction, normal load, and inflation pressure on dependency of tractive force upon longitudinal slip. The results show that tractive force is a determining factor in the modified tire resistance. In addition, it is seen that behavior of the modified tire resistance undergoes qualitative changes so that for a specified tractive force, it might be a strictly decreasing function of the mentioned parameters. But as the tractive force gradually increases, it might be changed to a non-monotonic function and after that to a strictly increasing function of the above parameters. Furthermore, the results are validated by measuring the vehicle constant-speed fuel consumption experimentally. History

“…The weighting process of a truck with a semitrailer is made on each axle, and the allowable values for each axle are the following: for the truck front axle is 7500 kg, the rear axle 11500 kg, while for the semi-trailer the total allowable mass is 8000 kg for each axle of the trident. In case of exceeding, the transportation company receives a fine, proportional with the exceeding [1], [2], [4].…”

Abstract. Due to the increasing number of heavy trucks, the number of the overweight trucks have increased, and most of them, were recorded with axle overweight. This may lead to fines for the transportation companies, and to the road damage. One of the main reasons of axle over-weight is the COG displacement, which is influenced by several factors. The main objective of this paper is to determine the way that a suspension setting can influence the cargo load distribution inside a truck-semi-trailer assembly. In order to achieve the proposed objective, a calculation principle in regarding to the influence of the suspension setting upon the axle weight distribution for heavy trucks is presented. This calculation method was validated through experimental tests. The results indicates that the suspension setting plays a great role in the uniformly distribution of the cargo load, and using a wrong suspension setting, overloading on a certain axle may appear.
