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

Dell’Orto, G. (author), Mastinu, G. (author), Happee, R. (author), Moore, J.K. (author)The paper presents measurements of the lateral force and self-aligning torque from cargo and city bicycle tyres. Based on the experimental data, we have determined the parameters for the Magic Formula model, for lateral force and self-aligning torque. We performed tests with VeTyT, an indoor test rig specific for bicycle tyres, under...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

Dell'Orto, G. (author), Mastinu, Gianpiero (author)Bicycles are becoming always more popular as a cheap and healthy tool for urban travels. The concerns für crowded public transport means are changing the habits after the pandemic situation caused by Covid-19, encomaging people towards the use of bicycle. As stated in literature, tyres play a large role in the handling ofbicycles . This is why...conference paper 2022

Berge, S.H. (author), de Winter, J.C.F. (author), Hagenzieker, Marjan (author)Interpreting the subtleness and complexity of vulnerable road user (VRU) behaviour is still a significant challenge for automated vehicles (AVs). Solutions for facilitating safe and acceptable interactions in future automated traffic include equipping AVs and VRUs with human-machine interfaces (HMl.s), such as awareness and notification systems,...conference paper 2022

Yang, Z. (author), Zhang, P. (author), Moraal, J. (author), Li, Z. (author)By modifying friction to the desired level, the application of friction modifiers (FMs) has been considered as a promising emerging tool in the railway engineering for increasing braking/traction force in poor adhesion conditions and mitigating wheel/rail interface deterioration, energy consumption, vibration and noise. Understanding the...journal article 2022

(author), Goraj, Zdobyslaw (author), Kowalski, Mariusz (author)Key results from the EU H2020 project CENTRELINE are presented. The research activities undertaken to demonstrate the proof of concept (technology readiness level-TRL 3) for the so-called propulsive fuselage concept (PFC) for fuselage wake-filling propulsion integration are discussed. The technology application case in the wide-body market...journal article 2021

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

Naeimi, M. (author)Rolling contact fatigue (RCF) is an important form of damage in wheels and rails that typically has surface and subsurface cracks. Squats are one of the major RCF defects that occur in the running band of rails and can create high dynamic forces and cause rail fracture if they are not detected and treated in time. In the current research, three...doctoral thesis 2020

Naeimi, M. (author), Li, Z. (author), Petrov, R.H. (author), Sietsma, J. (author), Dollevoet, R.P.B.J. (author)A new downscale test rig is developed for investigating the contact between the wheel and rail under impact-like loading conditions. This paper presents the development process of the setup, including review and synthesis of the potential experimental techniques, followed by scalability, mechanical and operational analysis of the new setup. The...journal article 2017

Naeimi, M. (author), Li, Z. (author), Petrov, R.H. (author), Dollevoet, R.P.B.J. (author), Sietsma, J. (author), Wu, J. (author)The substantial similarity of fatigue mechanism in a new test rig for rolling contact fatigue (RCF) has been investigated. A new reduced-scale test rig is designed to perform controlled RCF tests in wheel-rail materials. The fatigue mechanism of the rig is evaluated in this study using a combined finite element-fatigue prediction approach. The...conference paper 2014

Naeimi, M. (author), Li, Z. (author), Dollevoet, R.P.B.J. (author)A new small–scale test rig developed for rolling contact fatigue (RCF) investigations in wheel–rail material. This paper presents the scaling strategy of the rig based on dimensional analysis and mechanical modelling. The new experimental rig is indeed a spinning frame structure with multiple wheel components over a fixed rail-track ring,...conference paper 2014

Wanhill, R.J.H. (author), Mom, A.J.A. (author), Hersbach, H.J.C. (author), Kool, G.A. (author), Boogers, J.A.M. (author)The NLR has two high velocity burner rigs for oxidation and hot corrosion testing. A large, custom-built rig was commissioned in 1977 to enable actual components to be tested. A smaller rig for specimen testing was purchased in 1986. Experience with these rigs over the last decade is reviewed.report 1989
