Acquiring accurate tire–pavement interaction information is crucial for pavement mechanical analysis and maintenance. This paper combines the tire finite element model (FEM) response surface methodology (RSM) to obtain analyze structure under different loading conditions. A set of experiments was initially designed through Box–Behnken design (BBD) method input output variables RSM calibration. ...

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...

Objective: It is believed that drivers play a crucial role in accidents. Paying attention to brake lights, a driver may find out about danger and react. Rear-end collision accidents refer to the part of the accidents due to driver inattention or slow reaction. The aim of this study was to determine the effect of dynamic flashing brake lights (7 Hz) on drivers' brake reaction time using the driv...

In this study, the effect of tire inflation pressure on vehicle during braking was investigated experimentally. The experimental study carried out in Brake-Suspension Test Device designed as a half-vehicle model, which enables brake tests to be performed laboratory. During tests, total nine different pressures from 26 psi 40 standard value were taken into consideration. As result experiments se...

The Anti-lock braking system (ABS) is the most common safety system in the vehicles, which works to increase the generating braking force between the tire and the road surface in way to keep the stability in vehicles during braking. The high nonlinearity due to the interaction between the tire and road, the uncertainties in vehicle dynamics always exist and using the standard PID controller wil...

The Digital Imaging and Remote Sensing Laboratory (DIRS) at the Rochester Institute of Technology, along with the Savannah River National Laboratory is investigating passive methods to quantify vehicle loading. The research described in this paper investigates multiple vehicle indicators including brake temperature, tire temperature, engine temperature, acceleration and deceleration rates, engi...

The Automobile Braking System has a crucial role for safety of the passenger and riding quality of the vehicle. The braking force mainly depends on normal reaction on the wheel and the coefficient of friction between the tire and the road surface. Whenever a vehicle is loaded, the normal reaction on the rear wheel is increased. Thus the amount of braking force required to halt the vehicle with ...

excessive production and stockpile of scrap tires cause some environmental and sanitary risks throughout the world. to manage these materials, possible use of soil-tire mixtures has been recently propounded in civil engineering projects. a few studies previously have been conducted to evaluate behavior of clay-tire mixtures, while swelling properties, consolidation and settlement characteristic...

This paper introduces a technique that relates the coefficients of the Magic Formula tire model to the physical properties of the tire. For this purpose, the tire model is developed by ABAQUS commercial software. The output of this model for the lateral tire force is validated by available tire information and then used to identify the tire force properties. The Magic Formula coefficients are o...

The need to regulate the non-exhaust particulate matter (PM) emissions from vehicles has been discussed worldwide due bad environmental impact and toxicity human body. In-depth studies have precisely conducted on analysis of matters, in particular, amount tire, brake road wear particles their proportion atmosphere. In this study, influence tire (TRWP) PM atmosphere was investigated with samples...
