Peter Torstensson

Forskare vid Chalmers, Mekanik och maritima vetenskaper, Dynamik

Peter Torstenssons forskning rör vibrationer på järnvägen och deras oönskade effekter. I fokus finns åtgärder för ett minskat järnvägsbuller. Arbetet omfattar allt från lågfrekvent buller orsakat av exempelvis ojämnheter på hjul och räl (korrugering) till högfrekvent broms- och kurvskrik. Han är även bihandledare i ett doktorandprojekt inriktat mot rullkontaktutmattningsskador på räls och hjul (squats). Peter undervisar inom ämnesområdena mekanik och hållfasthetslära.
