When a vehicle equipped with tire is manoeuvred on the ground, the tires are submitted to a number of forces – longitudinal force when driving or braking torque is applied to the wheel and/or lateral force when the wheel is steered to turn at a corner. Pacejka model describes these forces that represent the reaction of the road onto the tire. This nonlinear model depends on correlated parameter...

This paper describes an approach of how to estimate the vehicle velocity using additional sensors provided by the brake-by-wire actuators. The advantage of brake-by-wire actuators such as the electro-hydraulic (EHB) and the electro-mechanical brake (EMB) is that the caliper pressure or the clamping force, respectively, are known. Wheel speed, vehicle acceleration, and caliper pressure or clampi...

This paper presents an experimental study of the electronic differential system with four-wheel, dual-rear in wheel motor independently driven an electric vehicle. It is worth bearing in mind that the electronic differential is a new technology used in electric vehicle technology and provides better balancing in curved paths. In addition, it is more lightweight than the mechanical differential ...

A simplified, closed-form version of the basic mechanics of a driven rigid wheel on lowcohesion deformable terrain is presented. This approach allows the formulation of an on-line terrain parameter estimation algorithm, which has important applications for planetary exploration rovers. Analytical comparisons of the original and simplified equations are presented, and are shown to closely agree....

The railway industry has focused on the improvement of maintenance through use novel technologies. Recently, utilisation repair welding to restore worn area wheels been investigated, as it can bring significant savings in wheelset maintenance. Under an Innovate UK AURORA project, a wheel that previously operated London Underground (LUL) was restored using this process. To test its performance a...

this paper is composed based on the assumption that in order to reach creativity in design, methods of meaning creation and new concepts in humanities should be considered as important as methods of creativity in technical viewpoints. authors claim that lack of fruitful discussion and dialog between humanities and technical science in design had generated a problematic obstacle to creativity in...
