ABSTRACT
Four simple, low cost aerodynamic drag reduction devices have been developed for application to
the trailer of a tractor-trailer truck. Two vortex flow devices have undergone extensive
operational fleet testing where they have amassed over 85,000 miles of use. These two vortex
flow technologies have shown a combined fuel savings of 8% at an average speed of 47.5 mph.
This improvement in fuel economy correlates to an equivalent drag reduction of approximately
20% with a corresponding drag coefficient of 0.45. Observations ....etc

OPTIMIZATION OF CURE CYCLE TIME OF A BIAS TRUCK LUG TYRE BY STUDYING THE CURE EQUIVALENTS IN ISOTHERMAL AND NON-ISOTHERMAL CONDITIONS


INTRODUCTION
Curing is a process in which the viscoelastic rubber is converted into three-dimensional networks by tying up of all independent chains. Uncured rubber is a viscoelastic fluid, which has poor physical properties and undergoes deformation easily. Curing process reduces the flow of rubber material. And also reduces the amount of permanent deformation after the removal of deforming ....etc

The primary purpose of the tyre is to provide traction. Tyres also help the suspension absorb road shocks, but this is a side benefit. They must perform under variety of conditions. The road might be wet or dry; paved with asphalt, concrete or gravel; or there might be no road at all. The car might be traveling slowly on a straight road ,or moving quickly through curves or over hills. All of these conditions call for special requirements that must be present, at least to some degree, in all tyres. In addition to providing good traction, tyres a ....etc

ABSTRACT
Complex tyre behavior is a direct result of the tyre construction. While looking much like a simple rubber doughnut attached to the rim, the tyre construction is vastly more complex, the two main functions of the tyre, is force generation in the road plane and suspension of the vehicle mass. The force generation is made possible by the rubber tread, causing a high friction coefficient with the road surface. The suspension of the vehicle mass is managed by the belt, radial cords and beads. The ....etc

To most people tyres are air filled rubber rings a car runs on. But for the more analytically minded a tyre can have several definitions. Geometrically, it is a torus, mechanically it is a flexible membrane pressure container, structurally a high performance composite and chemically, a tyre is composed of long chain macromolecules. Every one of you in your life time have encountered with tyres in the form of punctures replacement sets and also in many other form, but, most of the people are not aware of what comprises the tyres or what actually ....etc
