Polygonal Wear of Automobile Tires.

Wireless Monitoring of Automobile Tires for Intelligent Tires

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...

Nondestructive Evaluation of Automobile Tires by Electronic Speckle Pattern Interferometry

Electronic speckle pattern interferometry (ESPI) was used for the evaluation of mechanical properties of automobile tires. The tire on wheel disc was fixed on the holder and its vibration was generated by loudspeaker. Vibrational field of the whole tire was visualized by ESPI and recorded into PC. Natural frequencies of various vibrational modes were measured and results were compared with thos...

Effects of Studded Tires on Pavement Wear and Traffic Safety

IN T R O D U C T IO N The question of whether the use of metal studs in automobile tires should be permitted as an aid to winter driving has been a highly controversial issue in Minnesota for a number of years. The state leg­ islature in biennial sessions had legalized their use on Minnesota roads and streets for six successive winters from October 1965 through May 1971. But during its last ses...

Application of the Finite Element Method to the Analysis of Automobile Tires

The ingredients required for computationally e cient large-scale 3D FE contact analyses of automobile tires are presented. A hybrid nite element is employed for describing the nearly incompressible behaviour of rubber. The reinforcing cords are represented numerically by means of rebar elements. Strategies for reducing the amount of CPU time and disk space are reported including an iterative so...
