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...

This paper describes various time-domain methods useful for analyzing the experimental data obtained from a circular cylinder force in terms of both wave and current for estimation of the drag and inertia coefficients applicable to the Morison’s equation. An additional approach, weighted least squares method is also introduced. A set of data obtained from experiments on heavily roughened circul...

An investigation was conducted to determine the influence of recycled scrap tire rubber on the engineering properties of controlled low strength material (CLSM). With control over the ultimate compressive strength of CLSMs being key for applications such as backfilling utility trenches where re-excavation is often necessary, incorporation of scrap tire rubber into the CLSM mixture is a viable w...

For the design of an antenna that will be directly attached to a car tire, the proximity effects due to the tire have to be considered. Measurements are performed on a dipole antenna that is mounted at the inside of the tire tread to determine the change in input impedance and resonant frequency caused by the dielectric rubber material and the metal reinforcement of the tire. A differential mea...

Laboratory studies were conducted to investigate scrap-tire-shreds as a potential alternative to conventional gravel in the drainage layer of leachate collection system at the base of landfill. Performance of various physico-chemical characteristics of leachate after passing it through combined bed of scrap-tire-shreds and gravel for different combinations of thickness of scrap-tireshreds and g...

Active steering systems can help the driver to master critical driving situations, for example aquaplaning and -split braking. In these situations it is likely that the tires reach their performance limits, where nonlinear effects like saturation play an important role. Tires are the part in vehicle dynamics afflicted with the highest degree of nonlinearity – due to saturation – and uncertainty...

A nonlinear tracking controller is presented in this paper for the haptic interface in steer-by-wire automotive systems. Specifically, the controller is designed to ensure that the steering mechanism (i.e., directional control assembly) follows the operator corn-rnanded maneuvers at the driver interface. Further, the controller provides the driver with tunable force feedback , proportional to t...
