RGR Road Models for <italic>FTire</italic>

Abstract

<div class="htmlview paragraph">The paper discusses the Regular Grid Road Model (RGR), being the preferred road description of the tire simulation model <i>FTire</i> (Flexible Ring Tire Model, <span class="xref">figure 1</span>, <span class="xref">figure 2</span>, [<span class="xref">1</span>]).</div> <div class="htmlview paragraph">RGR models are an alternative to triangulations. They provide considerable and scalable reductions in file size, in memory demand, in file loading time, and in CPU time for evaluation.</div> <div class="htmlview paragraph">The contribution presents and discusses different file formats, the combination with curved road center-lines, a loss-less file compression technique, a dynamic patch-loading technique, export of curved center-lines for simultaneous use in driver models, as well as tools for generation, processing, and visualization of RGR files.</div> <div class="htmlview paragraph">As an outlook, an efficient and versatile new interface to non-rigid road models will be suggested, to promote development and use of soft soil models together with <i>FTire</i>.</div>
