Abstract [sv]

Då godsvagnar skall vägas med trådtöjningsgivare monterade i järnvägsräls finns ett antal faktorer som inverkar på mätresultatet. Denna rapport utreder genom datorbaserade simuleringar hur underlag och hastighet inverkar på töjningen i rälsen och även i viss mån hur deformationen i rälsen påverkas. Vidare utreds hur störningar i form av temperaturförändring samt förändring av kontaktkraften mellan vagnshjul och räls inverkar på töjningen. Förändringen av kontaktkraften kan exempelvis bero på hjulplatta, vibrationer från godsvagn eller ojämnheter i rälsen.

Abstract [en]

When goods wagons are weighed out with a strain gage assembled to a rail there are certain factors that affect the results of the measurement. This report investigates by computer based simulations how the foundation and the speed of a wagon affect the strain and the deformation of a rail. Furthermore, in the report investigations are made how disturbances in the form of changes in temperature and changes of the contact force between the wheel of a wagon and the rail affect strain. The changes can occur due to non-round wheels, vibrations of a wagon or irregular rail.
