Andreas Almqvist

Forskning

Andreas jobbar med modellering och simulering av tribologiska kontakter. Tribologi handlar om ytor som rör sig relativt varandra och omfattar områdena nötning, smörjning och friktion. Forskningen är alltså inriktad på att ta fram teoretiska modeller (och tillhörande numeriska lösningsmetoder) som gör det möjligt att i datorn simulera t ex hur smörjfilm byggs mellan kula och lagerbana i ett rullingslager. Exempel på andra intressanta tillämpningar är kontakten mellan kolvring och cylinder foder, den vägbanan och ett rullande/glidande däck och den i din egen höftled.
