Wheel numeric and different versions of mobility numbers are important models for predicting the rolling resistance. In this study, data related to the rolling resistance of cross ply and radial ply tires were compared with the resultant values from several models. Also, the preciseness of models in rolling resistance prediction was evaluated. For this purpose F test and 1-1 line method (p≥ 0.0...

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. ...

Tread design has evolved over the years to achieve the common tread pattern used in current vehicles. However, to meet safety and comfort requirements, tread design considers more than one design factor. Tread design must consider the grip and drainage, and the manner in which to reduce rolling noise, which is one of the main factors considered by manufacturers. The main objective of this study...

A balance platform setup was defined for use in the determination of the center of gravity in the sagittal plane for a wheelchair and patient. Using the center of gravity information, measurements from the wheelchair and patient (weight, tire coefficients of friction), and various assumptions (constant speed, level-concrete surface, patient-wheelchair system is a rigid body), a method for estim...

Sustainable power supply to flexible electronics is currently of high interest due the transition autonomous and self-driving vehicles. Piezoelectric Energy Harvesters (PEH) can be used as sustainable energy sources by harvesting electrical through material deformation occurring in a tire. In this work, an analytical setup was developed experimentally validate harvesters for their use tires. It...

This paper deals with the modeling of rolling resistance and analysis effect pavement texture. The Rolling Resistance Model (RRM) is a simplification no-slip rate Dynamic Friction (DFM) based on tire/road contact intended to predict tire/pavement friction at all slip rates. experimental validation this approach was performed using machine simulating tires road surfaces. tested surfaces have wid...
