A nonlinear model consisting “yaw, roll, longitudinal, lateral and pitch” has been developed in which, tire and suspension characteristics have been considered. Tire model is based on the elliptic concept and tire Calspan data. According to this tire model, cornering force and aligning moment are computed as a function of slip and camber (inclination) angles, normal load, tire adhesion characte...

Two separate topics of work are outlined: methods for the measurement of chlorinated monomers in PVC and polychloroprene, and also methods for the measurement of these materials in factory air. Typical results which have been obtained in supplies of raw materials, in finished products, and in the working atmosphere at manufacturing operations are given. The second topic concerns the measurement...

Tire cavity noise refers to the vehicle noise due to the excitation of the acoustic mode of a tire air cavity. Although two lowest acoustic modes are found to be sufficient to characterize the cavity dynamics, the dynamical response of these two modes is complicated by two major factors. First, the tire cavity geometry is affected by the static load applied to the tire due to vehicle weight. Se...

In 1985, the scrap tire industry was created when Minnesota became the first state to develop specific legislation and regulations for scrap tires. Up to that time, many scrap tires, like most solid and household wastes, went into the l1)unicipal dump. Those tires not placed in the dump went into stock piles, some of which still exist today. Prior to 1985, few, ifany scrap tires were processed....

i’ire behaviour plays a very important role in vehicle dynamic studies. Because of the complexity of tire structure, some tire models use so many assumptions they cannot represent tire behaviour well, while others are so complicated they are di@icult to use in engineering applications. This study presents an analytical tire side slip modeI with flexible tire carcass which is very helpful for un...

The heavy vehicle industry has today no requirement to provide a tire pressure monitoring system by law. This has created issues surrounding unknown tire pressure and thread depth during active service. There is also no standardization for these kind of systems which means that different manufacturers and third party solutions work after their own principles and it can be hard to know what work...

backgrounds and aims: semi automated processes of iranian tire manufacturing factories lead to significant occupational exposures to benzene and toluene compounds. this study was conducted to evaluate the magnitude and risk of workers exposures. materials and methods: personal monitoring of 100 workers (10 groups) was performed using niosh method no.1501 in two tire manufacturing factories in t...

The textile industry is one of the most important consumer goods industries worldwide. Its mostly small and medium-sized enterprises produce textiles for various uses such as clothing, home textiles (such as bed and table linen, kitchen towels and cleaning rags), household textiles (such as curtains, furniture fabrics, textile floor coverings) and technical textiles (such as protective clothing...
