This study investigated the properties and sustainability of cement-bonded composites containing industrial residues such as wood chips, tyre fibres biomass combustion residues, i.e. bottom ash (BA) fly (FA). The effect cement-to-raw material (wood/tyre fibre) ratio (C/RM) aggregate content (BA FA) on thermal mechanical were investigated. Scanning electron microscopy (SEM) life cycle analysis (...

The Anti-lock braking system (ABS) is an active safety device in road vehicles, which during hard braking maximizes the braking force between the tyre and the road irrespective of the road conditions. This is accomplished by regulating the wheel slip around its optimum value. Due to the high non-linearity of the tyre and road interaction, and uncertainties from vehicle dynamics, a standard PID ...

Loss of braking power and rubber skidding on a wet road is still an open physics problem, as neither the hydrodynamic effects nor the loss of surface adhesion that are sometimes blamed really manage to explain the 20-30% observed loss of low-speed tyre-road friction. Here we report a novel mechanism based on sealing of water-filled substrate pools by the rubber. The sealed-in water effectively ...

This paper presents the modelling and simulation of a stable angle-based instability threat indicator for articulated off-road vehicles. First, a stable angle is represented by the vertical forces of four wheels and steering angle of an off-road articulated steer vehicle. Then a vehicle prototype model is built based on a specific wheel loader type and a tyre/terrain model. Finally, the prototy...

Abstract The production of tyres is one the most energy consuming manufacturing activities in rubber sector. In cycle a tyre, curing operation has maximum loss. This mostly due to extensive use steam as source heat and pressure vulcanization process. To author’s knowledge, no scientific work available literature where efficiency tyre press estimated by means comprehensive model all main compone...

The car-tyre friction injury has differences from other injuries. The components of injury which are burn, crushing, shearing, and degloving occur. Many treatment options can be performed for coverage of wound which are Vacuum Assisted Closure system (V.A.C), skin grafting, free flaps, local flaps and cross leg flap.

In this paper, a new cascaded wheel-slip control strategy based on wheel slip and wheel acceleration measurements is presented. This new algorithm is able to stabilize globally and asymptotically the wheel slip around any prescribed setpoint, both in the stable and unstable regions of the tyre.

background:  the purpose of this study was to report the preoperative complaints and postoperative outcome of patients after removal of the radial head prosthesis.   methods:  this is a retrospective review of 14 adult patients (6 females and 8 males) from 2007 to 2011, who underwent radial head prosthesis removal by three surgeons. the average time between implantation and removal was 23 month...

The multibody dynamics analysis software, AUTOSIM, is used to develop automated linear and nonlinear models for the hand derived motorcycle models presented in (Sharp, 1971, 1994b). A more comprehensive model, based on previous work (Sharp and Limebeer, 2001), is also derived and extended. One version of the code uses AUTOSIM to produce a FORTRAN or C program which solves the nonlinear equation...

Abstract NPTs have vast applications because of no tyre puncture, need for air pressure, low rolling resistance, and also higher flexibility design recyclability. In this research work, different structures polyurethane (PU) spokes been designed analyzed under radial loading conditions which include like honeycomb with varying cell angles, simple spoke, trapezoid type by keeping in view that th...
