Zhang, P. (author), He, C. (author), Shen, C. (author), Dollevoet, R.P.B.J. (author), Li, Z. (author)Wheel-rail high-frequency interaction is closely related to the formation of railway short-wave defects. Finite element (FE) method has been widely used to simulate wheel-rail dynamic systems, but its validity in modelling high-frequency interaction has not been fully demonstrated in three dimensions (3D). This work aims at comprehensively...journal article 2024

Zhang, P. (author), Li, Z. (author)This paper presents an experimental study on the development mechanism of short pitch corrugation using an innovative downscale V-Track test rig. Rail corrugation is reproduced in the V-Track with two wavelengths of 6.4 mm and 8.9 mm. Based on the measured wheel-rail contact forces, track dynamic behaviors, and observations, the consistent...journal article 2023

Zhang, P. (author), Moraal, J. (author), Li, Z. (author)An innovative downscale test rig called V-Track has been constructed for wheel-rail contact experiments under impact loading conditions. In this paper, a force measurement system termed a dynamometer was developed in V-Track to measure the wheel-rail contact forces. The dynamometer consists of four 3-component piezoelectric force sensors and...journal article 2021
