Abstract This article describes determining methods of metal emissions in the composition small particles coming by brake mechanisms details and tire wear as a result vehicle movement, dust to be formed comparative analysis on asphalt-concrete roads different compositions. A significant contributor particulate matter cities is traffic-related sources. Traffic-related can divided into exhaust re...
Introduction The EPA's PART5 model, similar in structure to the MOBILE5a model, calculates g/mi exhaust emissions of PM and SOx from 12 classes of motor vehicles. It also calculates g/mi emissions of road dust and particles from tire wear and brake wear1. The g/mi emission factors of PART5 can be multiplied by estimates of VMT in a particular region to produce a total inventory of mobile-source...
UNLABELLED Road transport emissions are a major contributor to ambient particulate matter concentrations and have been associated with adverse health effects. Therefore, these emissions are targeted through increasingly stringent European emission standards. These policies succeed in reducing exhaust emissions, but do not address "nonexhaust" emissions from brake wear, tire wear, road wear and ...
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...
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...
ti-6al-4v titanium alloy has great application in medicine and military industries due to its capabilities, namely high strength to weight ratio and corrosion resistance. in the current research, the effect of aging treatment on microstructure and wear behavior of ti-6al-4v titanium alloy was investigated. pin on disk wear test was applied to assess the wear behavior. specimens were first solut...
