In this paper, we present the development of a tire rubber deformation sensing system that provides the critical information for understanding and estimation of wheel/ground interactions for mobile robots and vehicles. Polyvinylidene fluoride (PVDF)based sensors are designed and fabricated to embed on the inner tread surface to measure the tire rubber tread deformation. Analytical models of the...

A change in the relative proportions of a mixture of rubber tire dust and rice husks will cause a change in the mixture’s electrical permittivity and its ability to absorb electromagnetic energy. An openended coaxial probe was used in conjunction with three dielectric mixture equations (the Kraszewski equation, the Landau equation and the Lichtenecker equation) to obtain the dielectric properti...

  Background : Various factors such as occupational and environmental risk factors affect blood pressure. Nowadays, shift work is a common work schedule. Studies on effect of shift work on hypertension showed different results. We studied the effect of shift work on hypertension and pre-hypertension among workers in a rubber manufacturing company.   Methods : In a cross-sectional study, 265 wor...

Shredded rubber tire is a geomaterial that is potentially useful in environmental and engineering projects. Here, we study the effect of particle size ratio on the thermal conductivity of granular mixtures containing rubber tire particles. Glass beads were mixed at various volume fractions with rubber particles of varying size. The 3D network model analysis using synthetic packed assemblies was...

The dissipated energy from periodic deformation is regarded as the main reason for heat generation and temperature rise inside the tire domain. However, the mechanical behavior of rubber parts is highly temperature dependent. In most performed investigations, the influence of thermal effects on stress/ deformation fields of pneumatic tires is ignored and just temperature distribution is conside...

one of the most important factors that affect tire friction is surface roughness, which determines the size of the real contact area, real pressure distribution on the contact interface, and scales of mechanical engagement between viscoelastic rubber and a rough substrate. the need to predict coefficient of friction (cof) for rubber on rough surfaces for applications such as traction of tires o...

BACKGROUND Work-related skin disease is common but few cases are documented in statutory reports or disability systems. Voluntary reporting by specialist physicians provides more complete information. AIMS To summarize incidence rates of work-related skin diseases reported by consultant dermatologists and occupational physicians, with emphasis on contact and allergic dermatitis by occupation ...
