The emergence of high-fidelity vehicle and tire models has raised the requirements for terrain measurement capabilities. Inaccuracies that were once tolerable for measurement of general terrain roughness are no longer acceptable for these new applications. The techniques in this work seek to improve the quality of terrain measurement in addition to providing an objective way to describe the acc...

Background & objectives: Environmental pollutants have detrimental effects on the reproductive function of human being and of animals. This study was aimed at evaluating the effects of tire debris, a fraction of particulate matter derived from tire wear, on motility and morphology of human spermatozoa. Methods: spermatozoa from ten healthy men were incubated for 4 hours with 10, 50 and 75 μg/ml...

This paper investigates kinetic behavior of a planetary rover with attention to tire-soil traction mechanics and articulated body dynamics, and thereby study the control when the rover travels over natural rough terrain. Experiments are carried out with a rover test bed to observe the physical phenomena of soils and to model the traction mechanics, using the tire slip ratio as a state variable....

INTRODUCTION There have been no reports in the literature of esophageal rupture in adults resulting from an explosion of an automobile tire. We report the first case of just such an occurrence after an individual bit into a tire, causing it to explode in his mouth. CASE PRESENTATION A 47-year-old Han Chinese man presented with massive hemorrhage in his left eye after he accidentally bit an au...

This paper presents a parametric design system for 3D tire mold production. Tire grooves commonly used in the current industry are classified according to their modeling procedures, and the design parameters for each groove type are characterized. The result serves as a foundation for standardization of the tire mold design. The presented system simplifies the construction of 3D groove surfaces...

Tire slip angle is a vital parameter in tire/vehicle dynamics and control. This paper proposes an accurate estimation method by the fusion of intelligent tire technology machine-learning techniques. The equipped MEMS accelerometers attached to its inner liner. First, we describe system along with implemented testing apparatus. Second, experimental results under different loading velocity condit...
