Analyse: Het effect van rubber op de grip van een circuit

Het Korea International Circuit nabij Yeongam was in 2010 het circuit waarop het meeste tijdwinst geboekt werd tussen de eerste vrije training en de kwalificatie. De pole-tijd van zaterdagmiddag was maar liefst 5,3 seconden sneller dan de beste tijd uit de eerste sessie op vrijdagochtend. Dat is het gevolg van het proces van inrubberen van het circuit; de grip die het wegdek biedt neemt tijdens het weekend toe naarmate er meer rubber op de ideale lijn komt.

Mercedes GP analyseerde dat proces in de aanloop naar de tweede Grand Prix van Zuid-Korea. Het effect van de zachtheid van de band is groter dan de temperatuur. Hoe zachter de band, hoe meer rubber het achterlaat op de lijn. Een belangrijke factor voor de mate van inrubbering is de hoeveelheid bochten. Dat blijkt uit de cijfers van het weekend in Zuid-Korea van vorig jaar. In de eerste sector ging de tijd in 2010 met 3,2 procent vooruit, ten opzichte van 6,2 procent en 6,7 procent verbetering in respectievelijk de tweede en derde sector. De eerste sector van Korea International Circuit heeft beduidend minder bochten dan de twee andere sectoren.

Stratencircuits rubberen over het algemeen het meeste in gedurende een Grand Prix-weekend. Dat heeft ook te maken met het vuil dat steeds meer van de ideale lijn weggereden wordt. Monaco staat bovenaan in die lijst, met Melbourne, Singapore en Valencia als goede achtervolgers. De rondetijd daalt op die banen rond de 5,5 procent – ongeveer vijf seconden – van de eerste vrije training richting de kwalificatie.

    Leuke analyse, maar het effect van het \&quot;inrubberen\&quot; is met de Pirelli banden een stuk minder dan met de Bridgestones het geval was. De Pirelli\'s slijten namelijk op een andere manier dan de Bridgestones reden. Je ziet nu meer stukjes rubber naast de racelijn liggen in plaats van donkere strepen op de racelijn.

    Niet geheel onverwacht dat Monaco, Singapore, Valencia en Melbourne bovenaan staan. Bij stratencircuits is er natuurlijk veel meer rotzooi op de baan dan op de andere circuits. Ben meer benieuwd naar de verhoudingen van de andere banen.
