Experimental and Numerical Investigation into Formation of Metro Wheel Polygonalization
We present a detailed investigation of the mechanism of metro wheel polygonal wear using on‐site experiments and numerical simulation. More than 70% of metro wheels exhibit 6th–8th harmonic‐order polygonal wear; the excitation frequency of the polygonal wear is located in the 50–70 Hz interval at an operating speed of 65–75 km/h.

Estimation of Cement Asphalt Mortar Disengagement Degree Using Vehicle Dynamic Response
Cement asphalt mortar (CA) disengagement of a ballastless track will induce changes of dynamic response of a passing vehicle, which can accordingly be used to estimate the disengagement degree. In this paper, a novel method called CA mortar disengagement degree estimation algorithm (CMDEA) is proposed through an analysis of wheel acceleration of a ...
