Safety testing of railway vehicles is, according to international regulations, based on measurements of accelerations of axis and forces acting at rail-wheel contact. While acceleration measurements represent standard methodology, only small number of countries has developed methodologies for measurement of forces acting at wheel-rail contact. This paper presents analysis of stresses and deformations of wheelset and standard wheels needed for design of new type of sensors which will efficiently measure forces in wheel-rail contact.
