On the Simulation of Powered Axles Stick-Slip
Autor: Cornelia Stan, Razvan Andrei Oprea, Cristina Tudorache
Publikováno v: Applied Mechanics and Materials. :610-615
The use of high power railway vehicles requires enhanced control of wheel-rail adherence. When setting the train in motion, driving axles can exhibit torsional vibrations resulting in poor adherence and even axle damage. A significant number of railw

A Method of Analyzing the Contact between the Wheel and the Railway
Autor: Ioan Sebesan, Mihela Cristina Tudorache
Publikováno v: Applied Mechanics and Materials. :1109-1114
Through the past years numerous theories regarding the contact between the wheel and the railway have been created with the purpose of resolving the interaction issues and improving the dynamical performances of the vehicle. In this context the paper

Using the Green’s functions method to study wheelset/ballasted track vertical interaction
Autor: Mdlina Dumitriu, Traian Mazilu, Mircea Sebesan, Cristina Tudorache
Publikováno v: Mathematical and Computer Modelling. 54(1-2):261-279
This paper presents an application of the Green's functions method in the field of the wheelset/track interaction using a new model of the periodic support of the rail that improves the prediction for both low and high frequencies. The track is reduc

On the dynamics of interaction between a moving mass and an infinite one-dimensional elastic structure at the stability limit
Autor: Cristina Tudorache, Mădălina Dumitriu, Traian Mazilu
Publikováno v: Journal of Sound and Vibration. 330:3729-3743
The paper herein deals with the study of the dynamic behaviour generated by the instability of the vibration of a loaded mass, uniformly moving along an Euler–Bernoulli beam on a viscoelastic foundation, induced by the anomalous Doppler waves excit

An analysis of the train–turnout interaction
Autor: Mihaela Cristina Tudorache, Razvan Andrei Oprea
Publikováno v: MATEC Web of Conferences, Vol 112, p 07023 (2017)
A distinctive feature of the application proposed in this work is the occurrence of simultaneous contact patches on a single wheel, i.e., the multi-point contact case. A difficulty in the study of this phenomenon is that the contact areas depend on t

Wheel-rail joint geometry
Autor: Mădălina Dumitriu, Traian Mazilu, Cristina Tudorache, Mircea Sebesan
Publikováno v: 4th International Workshop on Soft Computing Applications.
This paper deals with the geometric issue of the contact between a wheel and a rail joint. A new model in this field is proposed. Actually, the wheel and rail elasticity is introduced in order to overcome the singularity of the contact force that is
