Abstract
In research into the polygonization of rail vehicle wheels, vibrations in the vehicle/track system are considered to be possible root causes. The vibrations lead to alternating wear in the wheel-rail contact patch, which together with the wheel rotation leads to polygonal wear. When investigating these problems, it is essential to establish a connection between vibration frequency, driving speed and polygon order. However, with the polygonization cycle with several wheel revolutions, an approach has already been described that deviates from the established model concept. In this paper, various formulas are derived and their previous applications are analyzed in a meta-study. This includes the hypothesis of a doubling of the wear rate frequency relative to the vibration frequency, which can be caused by vibration modes that generate mainly lateral creep. Additionally, the plausibility of the frequency doubling is checked by multi-body simulations.
