An extension of the LuGre dynamic friction model from longitudinal motion to longitudinal/lateral motion is developed. Applying this model to the motion of a tire we derive a model for tire-road contact forces and moments. A comparison of the steadystate behaviour of the dynamic model with existing static tire friction models is also presented. This comparison allows one to determine the values...

INTRODUCTION Tire explosion injuries are rare, but they may result in a severe injury pattern. Case reports and statistics from injuries caused by exploded truck tires during servicing are established, but trauma from exploded small tires seems to be unknown. CASE PRESENTATION A 47-year-old german man inflated a wheelbarrow tire. The tire exploded during inflation and caused an open, multiple...

Several technologies established for tire utilization were reviewed in order to determine the best use of discarded tires. The technologies reviewed were retreading, reclaiming, splitting, combustion, pyrolysis, use in breakwaters, erosion control structures, reefs, pavements, general construction materials, etc. Based on the information collected, it was concluded that the use of discarded tir...

Wheeled-mobile robots operating in human environments typically encounter small steps. Surmounting steps is normally not considered when determining peak torque needs, yet it can be the maximum requirement. This work looks at the statics and dynamics of this situation to determine the necessary peak torque. It finds that using a dynamic model that includes the wheel elasticity is essential for ...

Forward integration has been explained both as a method of achieving monopoly power and as a source of greater efficiency [6, 16]. An efficiency perspective underpins the work of Chandler and Williamson who regard vertical integration, particularly into distribution, as a crucial step in the creation and success of large firms. While their views have moved closer, Chandler and Williamson emphas...

Continuously seeking the improvement of environmental protection, limitation exhaust emissions is significance for tire manufacturing industry. The aim this study to assess potential biofiltration treatment such gaseous emissions. This work highlights that able remove both hydrophilic and hydrophobic compounds within a single pilot unit biofiltration. Due Ethanol/Alkanes ratios (95/5 80/20), hi...

It is often difficult to measure all necessary parameters directly in the current stability control systems. This paper presents a nonlinear observer to estimate vehicle’s yaw rate, lateral acceleration, tire side slip angles and the road friction coefficient based on the measurement signals of the Electric Power Steering (EPS) system and the Anti-lock Braking System (ABS). The performances of ...

Comparison of static and dynamic control allocation techniques for nonlinear constrained optimal distribution of tire forces in a vehicle control system is presented. The total body forces and moments, obtained from a high level controller, are distributed among tire forces, which are constrained to nonlinear constraint of saturation, through two approaches. For the static control allocation te...

This review discusses key technologies of intelligent tires focusing on sensors and wireless data transmission. Intelligent automobile tires, which monitor their pressure, deformation, wheel loading, friction, or tread wear, are expected to improve the reliability of tires and tire control systems. However, in installing sensors in a tire, many problems have to be considered, such as compatibil...
