Self-Excited Full-Vehicle Oscillations Caused by Tire–Road Interaction: Virtual and Real-World Experimental Investigation

ABSTRACT In this article, self-excited full-vehicle oscillations (power-hops) are introduced. Initially, results of full-vehicle measurements are shown followed by the presentation of a specially build test rig (longitudinal dynamics test rig). Subsequently, these oscillations are investigated by using simulation-based tools within multibody simulation–related full-vehicle modeling. Tire–road interaction is evaluated in this process either by characteristic curves or by a proprietary quasistatic tire model that returns overall tangential forces by evaluating the state of every discretized element within the footprint area.

Continuously Variable Transmission Vehicle Modeling and Control Algorithm Considering Fuel Efficiency and Driveline Efficiency

The device presented in this paper was designed in order to give a hand to the deaf-mute community, by helping them to reintegrate in the society, using the modern technologies. We aim at manufacturing an intelligent glove based on the use of sensors in order to obtain a communication bridge with a decent speech level between the persons suffering hearing loss and the persons with normal hearing. The development and design of the glove represents an endeavor that aims at obtaining pertinent data from fingers’ motion. The prototype functionality can be easily compared with gloves for virtual applications as they work on the same principle, namely sensory activity and test subjects will verify the concept objectives.
