The cross-country capability of multi-purpose wheeled vehicles is one the most important operational properties these technical objects. In many ways, it determined by their traction characteristics. There are a number ways to improve and coupling multipurpose vehicles, main ones use various kinds control systems, blocking interaxle interwheel differentials, ballast several others. Recently, ab...

Hydroplaning is a unique phenomenon in which the water on a wet runway or highway is not displaced from the nominal tire-ground contact area by a rolling tire or by a moving but nonrotating (full-skidding) tire at a rate fast enough to allow the tire to make contact with the ground surface over its complete nominal footprint area, as would the case of operation on a dry surface. When hydroplani...

As we all know, the tire acoustic cavity resonance noise (TACRN) can cause irritating in a vehicle, but it is evidently difficult to be weakened. To obtain accurately characteristics of TACRN key step attenuating TACRN. In this paper, simulation method, which simplified finite element model automobile with introducing rotation established, proposed gain sound field rotating tire. And test press...

The coupling effect between tire and pavement is an intensively researched subject to analyse the dynamic interaction of the vehicle-pavement system. By considering the 11.00 R20 tire and expressway asphalt pavement, ABAQUS software was employed in this study to establish an improved model for simulating the coupling effect, in which the tire rubber was taken as a neoHookean material and the pa...

A nonlinear model consisting “yaw, roll, longitudinal, lateral and pitch” has been developed in which, tire and suspension characteristics have been considered. Tire model is based on the elliptic concept and tire Calspan data. According to this tire model, cornering force and aligning moment are computed as a function of slip and camber (inclination) angles, normal load, tire adhesion characte...

Currently, in the United States there is a growing gap between domestic oil production and consumption. The Department of Energy has developed a modeling tool (known as VISION) that projects future consumption by the transportation sector through the year 2050. This paper uses the VISION model to show that an energy savings of 3.8 billion gallons per year can be achieved with a 2.5% improvement...
