The tire-road friction coefficient is critical information for conventional vehicle safety control systems. Most previous studies in tire-road friction estimation have only considered either longitudinal or lateral vehicle dynamics which tends to cause significant underestimation of the actual tire-road friction coefficient. In this paper, the parameters, including the tireroad friction coeffic...

This paper investigates slip-based traction control of a planetary rover that travels over natural rough terrain. Special attention is made on tire-soil traction mechanics and articulated body dynamics. Experiments are carried out with a rover test bed to understand the physical behavior of tire-soil interaction and, thereby, a traction model is investigated using the tire slip ratio as a state...

Disposal of used tires has been a major problem in solid waste management. New uses will have to be found to consume recycled tire products. One such proposed use is as ground cover in playgrounds. However, concern has been expressed regarding exposure of children to hazardous chemicals and the environmental impact of such chemicals. We designed a comprehensive hazard assessment to evaluate and...

The paper considers an empirical approach to the root-cause analysis of a certain kind of automobile tire failure. Tire life data are obtained from a laboratory test, which is developed to duplicate field failures. A number of parameters related to tire geometry and physical properties are selected as explanatory variables that potentially affect a tire’s life on test. Analysis of the life test...

Simulation is an important aspect to consider when designing an inspection system based upon machine vision. The tire inspection system uses thermal cameras to inspect the surface of a tire. The simulation of a tire inspection system can yield an optimal set of parameters for a thermal camera, or given a specific thermal camera provide information on the optimal placement of the camera. Since t...

In order to improve the precision of the tire pressure monitoring system, the Bayes method is applied to establish its mathematical model of multi-sensor information fusion. The temperature and pressure in the tire, which are the complementary information, are integrated in the model through analyzing the mechanism of tire burst generated by temperature and pressure. Through the temperature com...

Cement production is highly energy intensive and requires large quantities of fuels. For both economical and environmental reasons, there is an increasing tendency for utilization of alternative fuels in the cement industry, examples being tire derived fuels, waste wood, or different types of industrial waste. In this study, devolatilization and combustion of large particles of tire rubber and ...

This paper presents an effectively unbiased nonlinear estimation scheme which identifies tire longitudinal stiffness and effective radius using GPS and ABS wheelspeed sensors. This estimation strategy is then used to experimentally identify the longitudinal stiffness and effective radius of a summer tire and a winter tire under several different test conditions. The data clearly shows that ther...

Tire text and geometry detection are used in scanning tires in order to identify the tire type and classify them according to a code printed on the sidewall which is called “DOT Code” then checking the treads whether they are defected or not based on the pattern periodicity of them. Classification is done based on applying some image processing and pattern recognition techniques on both treads ...

This work presents a convenient and non-contact acoustic sensing approach for measuring ground vibration. This approach, which uses an instantaneous dynamic tire pressure sensor (DTPS), possesses the capability to replace the accelerometer or directional microphone currently being used for inspecting pavement conditions. By measuring dynamic pressure changes inside the tire, ground vibration ca...
