The effect of steering-system linearity, simulator motion, and truck driving experience on steering of an articulated tractor-semitrailer combination

Steering systems of trucks consist of many linkages, which introduce nonlinearities that may negatively affect steering performance. Nowadays, it is possible to equip steering systems with actuators that provide artificial steering characteristics. However, before new steering systems are deployed in real vehicles, evaluation in a safe and...

Effect of steering model fidelity on subjective evaluation of truck steering feel

The steering behaviour in a driving simulator has a significant influence on a driving realism. This study investigates the influence of the complexity of a steering-system model on the subjective assessment of truck steering feel in on-centre handling. Ten subjects drove a highway task with and without lateral wind disturbance with 4 steering...

Improving vehicle routing using traffic predictions

Vehicle routing through road networks is an important topic of research: time and money can be saved by reducing traffic jams, which would also reduce the burden on the environment. The problem of minimizing the travel time for a vehicle trip is easy to grasp but hard to solve, it is a highly complex shortest path problem. Our goal is to show...

Speeding up the CONTACT package by means of the Fourier transforms / Het versnellen van CONTACT-programmatuur met behulp van Fouriertransformaties

Het bedrijf VORtech maakt gebruik van de software CONTACT om problemen in de contactmechanica op te lossen. Maar de berekeningen kosten zo veel tijd dat er met hele grove discretisaties gewerkt wordt. CONTACT kan sneller gemaakt worden door de vele convoluties die het bevat, in het Fourierdomein te berekenen. De theoretische achtergrond hiervan...

Geometrically non-linear behaviour of a bar with shear deformation

This article consists of two parts. The first part (section 2) deals with the bar without bending deformation, in which only shear deformation occurs. Such a bar may serve as a simplified model for the frame in a high-rise building. To investigate the properties required of the model we will look in more detail at the behaviour of a single...
