Abstract EU tyre labelling rules have been applied since November 1st, 2012, to inform about the performances of tyres on fuel efficiency (rolling resistance), safety (braking on wet surfaces) and noise (external noise). The tyre labels help customers to make their purchase decisions by trade off on tyre performances and prices. Consequently, manufacturers have to engineer their products so that their tyres are classified on top of the label categories. Tyre rolling resistance involves in many kinds of tyre knowledge such as rubber formulations, tyre structures and tyre tread patterns. General

Abstract:

ABSTRACT Rolling resistance defined as energy loss per unit distance is well accepted by the tire science community. It is commonly believed that the dominant part of energy loss into heat is caused by the viscoelasticity of rubber compounds for a free-rolling tire. To calculate the rolling loss (hysteretic loss) into heat, a method based on tire forces and moments has been developed to ease required measurements in a lab or field. This paper points out that, by this method, the obtained energy loss is not entirely converted into heat because a portion of the consumed power is used to compensa

Abstract:

Abstract Increasing pressure over the last three decades to improve vehicle fuel economy and decrease emissions along with a strong sense of environmental stewardship has driven the tire and rubber industries to reduce tire rolling resistance. This has been accomplished while simultaneously improving other aspects of tire performance dramatically. Reductions in rolling resistance of 50% relative to 1980 levels have been realized, and efforts continue to decrease rolling resistance further. Laboratory measurement and empirical modeling of rolling resistance behavior have evolved substantially,

Abstract:

Abstract One of the methods for lowering of energy consumption in the drive mechanisms of long horizontal belt conveyors is to reduce belt indentation rolling resistances. These resistances depend on a number of factors: bottom cover properties, bottom cover thickness, belt design, idler diameter, load, speed and frequency at which the belt passes on the idler (indentation frequency), as well as on temperature. Determining how these factors influence indentation rolling resistances of various conveyor belt types is of great importance. The article describes a small-scale method for testing ind

<strong>Purpose.</strong> About one of the causes of slip rolling is known from the second half of the 19th century, it was believed that the slip resistance appears at the place of contact due to different speeds on the arc of contact.

However (for some unknown reason) it is ignored the fact that in practice in rolling bearings may rotate both the inner ring with a stationary outer one, and vice versa almost in equal relations.

Sometimes it is necessary to test how repair affects the properties of the car. These tests are carried out using a cylinder test stand. During the test the tyre is rolling between two cylinders of a small diameter. The question arises whether the rolling resistance of the tyre is the same as the rolling resistance when the wheel is rolling on the plane. If it is not the same what is the reliation between tyre resistances in these two cases? It is an important answer because the change of rolling resistance can affect consumption, the highest speed, engine power and other results of measuremen

Abstract A simple equation for tire rolling resistance in terms of whole-tire hysteresis ratio, tire load, and footprint dimensions has been developed from energetic considerations. The rolling resistances of a number of radial passenger and truck tires have been calculated using the equation, and the calculated values were successfully compared with the measured results. The general applicability of the equation was illustrated by predicting the rolling resistances of a wide range of tires—from an experimental HR78-8 minitire to a full size 11R24.5 truck tire.

People moving on wheelchairs overcome the forces of resistance such as: air resistance, resistance of the ascent, inertia force and rolling resistance force. Under certain conditions of use of the wheelchair, the only resistance that must overcome the driving force during the movement is the rolling resistance force. This situation occurs during uniformly rectilinear movement, on a flat level surface at speeds of up to 20 km/h, because at this speed the air resistance is negligible. Rolling resistance is mainly influenced by the mass of the rolling object and the rolling resistance coefficient

Belt conveyors, having high reliability and efficiency, are the main means of continuous transportation both in underground and in open-cast mining. Despite their numerous advantages, however, belt conveyors are expensive in maintenance. Therefore, improvements in the field of belt conveyor transportation largely focus on methods for lowering their power consumption. The energy consumption level of a belt conveyor depends on the motion resistances which occur during its operation.

Abstract:

For cold rolling process, the theoretical Bland-Ford-Hill model and Hitchcock model are used for the rolling force and roll flatten radius calculation. Friction coefficient and deformation resistance are calculated with empirical regression models. From rolling force model, the recalculation model for the friction coefficient and deformation resistance can be derived. After rolling, with actual measured data, friction coefficient and deformation resistance can be recalculated, and model parameter can be got by regression method. The practical application verifies that the accuracy of rolling f

Abstract:

Abstract The natural magnesium silicate, sepiolite (trade name Pansil), can partially substitute (up to 30%) for carbon black without important losses in physical properties and occasionally can improve them. In the NR-based compounds, as the substitution takes place, vulcanization times and Mooney viscosities decrease. Tear and abrasion resistances are lower. The same effects are observed in the SBR-based compounds, though in this case, the addition of a silane coupling agent (Silane A-189) counteracts the negative effects of the sepiolite, and the obtained values are clearly better than thos

Abstract:

The tendency in the past few years has been to introduce tyres with lower rolling resistance coefficients to the market. This paper presents a mathematical method for determining the rolling resistance coefficients variation depending on the speed. The method uses power balance which results from automobile dynamics while rolling on chassis dynamometer. The rolling resistance coefficients of tyres obtained through ‘drum test method’, for which the rolling resistance coefficients variation is known in terms of vehicle speed, are considered as reference values, while than rolling resistance coef

AbstractElectric vehicles are playing an increasingly important role in the agricultural sector. The selection of tyres for reducing energy loss due to rolling resistance is an important consideration in determining the viability of these vehicles. To date little is known about rolling resistance of small all-terrain vehicles. In this study a test rig was used to collect rolling resistance data for seven ATV tyres. The study verifies the relationship between normal load and rolling resistance and gives insight into some of the important considerations when selecting tyres for small off road ve

Abstract:

Vehicle’s sliding resistance mainly includes rolling resistance, air drag resistance and friction within the transmission, wheel bearings and other related components. Among those, rolling resistance and air drag always exist whenever vehicle is running, so they have great influence on vehicle’s dynamic performance and fuel economy. Therefore, it is important to determine vehicle’s rolling resistance coefficient and air drag coefficient quickly and accurately in order to operate vehicle properly and reduce the vehicle’s fuel consumption.

Abstract:

For at least 50 years, the interest in understanding and reducing the rolling resistance of pneumatic tyres has been growing. This interest is driven by the need to reduce vehicle fuel consumption and CO2-emissions, for environmental and economic reasons. The amount of rolling resistance generated depends on the vehicle type, tyre properties and operating conditions. The main objective of this literature review is to provide an overview of the most influential operating conditions with respect to rolling resistance, their effects and their connection to different measurement techniques.

The article deals with measuring the rolling resistance of two tires Mitas TS04 6.00-16 6PR and Mitas TS05 10.0/75-15.3 10PR on a concrete surface. The measurement was performed in a soil test channel which had to be adjusted for the given purpose. The tires were compared with each other based on the results of the rolling resistance coefficient calculation. The obtained individual values were approximated by linear functions and subsequently subjected to a statistical analysis—a test of the agreement of the regression coefficients of the two basic sets.

Abstract Low rolling resistance tires help optimize the economy of electric vehicle (EV) operation. Five types of EV tires were evaluated under cold weather conditions and compared with traditional winter tires in terms of traction and rolling resistance. Other contributions to vehicle resistance (brake drag, wheel bearing resistance, driveline resistance, and air drag) were also measured and used to estimate changes in total vehicle resistance and associated changes in range with temperature. At low speeds, tire rolling resistance is the primary contribution to increased vehicle resistance at

Abstract:

Even if it makes a smaller contribution than aerodynamic drag, rolling resistance plays a non-negligible role in the efficiency of human-powered vehicles, whether they are designed for daily commuting or to set speed records. The literature, experimental evidence and models show that the rolling resistance coefficient of cycling wheels strongly depends on the supported load, suggesting that the number of wheels and the load distribution could play a role in vehicle design and in road-test data analysis.
