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...
متن کاملNondestructive 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...
متن کاملTests of two new polyurethane foam wheelchair tires.
The performance characteristics of four 24-inch wheelchair tires are considered; one pneumatic and three airless. Specifically, two new airless polyurethane foam tires (circular and tapered cross-section) were compared to both a molded polyisoprene tire and a rubber pneumatic tire. Rolling resistance, coefficient of static friction, spring rate, tire roll-off, impact absorption, wear resistance...
متن کاملApplication 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...
