The behavior a pneumatic tire is analyzed and simulated using a finite element model. We calculate the elastic deformations in the contact area of a pneumatic tire touching the street for different friction conditions between tire and street. The simulations are compared with the experimental results. The comparison demonstrates that the overall deformation as well as the frictional behavior in...

The seasonal prevalence and container preferences of Aedes albopictus (Skuse) were studied in the park, Parque Mirador del Norte in Santo Domingo City, Dominican Republic, from January to December 1994. Tire ovitraps were set along a transect through the park and monitored weekly while two larval surveys were conducted in both the park and surrounding houses using standard entomological methodo...

This work presents a single-chip sub-mm3 wireless pressure sensor suitable for tire pressure monitoring. The dynamic behavior and safety of an automobile tire is closely dependent on its inflation pressure: maintaining the manufacturerrecommended pressure is essential to prevent tire failure, provide stability, improve fuel efficiency and tire-life, and to reduce CO2 emissions [1]. Thus, Tire-P...

Hydroplaning is a unique phenomenon in which the water on a wet runway or highway is not displaced from the nominal tire-ground contact area by a rolling tire or by a moving but nonrotating (full-skidding) tire at a rate fast enough to allow the tire to make contact with the ground surface over its complete nominal footprint area, as would the case of operation on a dry surface. When hydroplani...

a new anti-lock braking system (abs) for motorcycles is proposed in this study. it functions by processing the speed of the motorcycle tire in contact with the ground relative to the speed of the motorcycle itself and by calculating the slip ratio (λ) of the tire slipping on the ground while braking, and reducing it to a minimum which leads to increased controllability of the motorcycle and red...

The coupling effect between tire and pavement is an intensively researched subject to analyse the dynamic interaction of the vehicle-pavement system. By considering the 11.00 R20 tire and expressway asphalt pavement, ABAQUS software was employed in this study to establish an improved model for simulating the coupling effect, in which the tire rubber was taken as a neoHookean material and the pa...

A tire and landing gear test facility has been developed and incorporated into a Convair 990 aircraft. The system can simulate tire vertical load profiles to 250,000 lb, sideslip angles to 15 degrees, and wheel braking on actual runways. Onboard computers control the preprogrammed test profiles through a feedback loop and also record three axis loads, tire slip angle, and tire condition. The ai...

Discarded vehicle tire casings are an important artificial habitat for the developmental stages of numerous vector mosquitoes. Discarded vehicle tires degrade under ultraviolet light and leach numerous soluble metals (e.g., barium, cadmium, zinc) and organic substances (e.g., benzothiazole and its derivatives [BZTs], polyaromatic hydrocarbons [PAHs]) that could affect mosquito larvae that inhab...

─ In a tire pressure monitoring system in which a pressure censor and a transmit antenna are contained in a tire, electromagnetic simulations of radiations from carcass embedded tires are requested. However, it is difficult to accurately determine these shielding effects. In this study, methods for performing accurate electromagnetic simulation by adopting the MoM scheme are determined. In the ...

A simplified FE tire model has capability to solve a large deformation of a tire on a vehicle running simulation with acceptable computation time. We tried to simulate a vehicle cornering by using simplified FE tire models and a vehicle model which has a detailed kinematical structure of suspensions.1 Introduction Introduction of CAE in an automobile design is progressing in various fields, and...
