“…Finally, the rail corrugation will be created. Shortly afterwards, Kurzeck and Hecht 18,19 also carried out similar researches. In recent years, a variety of rail corrugation in subway lines have been deeply studied by Chen's research group, and these complicated rail corrugation phenomena have been reproduced successfully using the theory.…”

In Chinese metro lines, Vanguard fastener system is widely used as vibration damping fastener. However, the rails mounted with this fastener system are deeply affected by rail corrugation. The generation mechanism of corrugation wear at a metro track mounted with Vanguard fastening is revealed through the numerical simulation method. A finite element model including two rails, the track system, and a leading wheelset is set up. The parameter sensitivity analysis is conducted to identify the dominant factors affecting the rail corrugation. Then, the remedy method to suppress the corrugation wear is put forward on the basis of the parameter analysis results. The results indicate that the severe corrugation wear on the inner rail is attributed to the self-sustained vibration of the wheelset–track system aroused by the saturated wheel–rail creep force. The frequency of the rail corrugation calculated by the model is very close to the measured data. The elastic modulus and the damping coefficient of the rubber rest pad in the Vanguard fasteners have a high impact on rail corrugation. Increasing the elastic modulus and the damping coefficient can effectively restrain or even eliminate the rail corrugation. Bringing the damping coefficient of the rubber rest pad above 0.0001 can significantly alleviate the rail corrugation. The influence of the damping and stiffness of the rubber pad under the floating slab track bed is negligible.

“…In their study, a finite element model of a wheel set-track system was established and analysed using the complex eigenvalue method. Kurzeck et al [18] and Kurzeck [19] established a friction coupling model of a vehicle-track system with three degrees of freedom. They studied the effect of frictioninduced vibration of a vehicle-track system on rail corrugation.…”

Two dynamic models of a wheel set-track system on a tight curved track and on a straight track are established, in which the friction coupling between the wheel and rail is taken into account. Both the transient dynamic and complex eigenvalue analyses are performed to study the unstable transient dynamics and stability of the wheel set-track system. It is assumed that in the models creep forces between wheels and rails are saturated, that is, approximately equal to the normal forces multiplied by the dynamic coefficients of friction. The simulation results demonstrate that the saturated creep force can induce self-excited vibration of the wheel set-track system. The normal contact force between the wheel and rail fluctuates at the same frequency as the wheel and rail vibrate when the self-excited vibration occurs. And the fluctuation frequency of the normal contact force falls into the range of 60-500 Hz, which corresponds to the frequency range of rail corrugation. This phenomenon indicates that the self-excited vibration of the wheel set-track system may be a main cause of rail corrugation occurrence. Parameter sensitivity analysis shows that the stiffness and damping of the rail fastener have important influences on the oscillation amplitude of the normal contact force. Bringing the friction coefficient below a certain level and increasing the damping of the rail fastener can suppress rail corrugation.

“…The main reasons for not showing these results are other than lateral dynamics co-ordinates dynamical quantities particular authors are interested in or velocities below the critical one. Example publications of such type are [30][31][32][33][34][35][36][37][38]. The interesting subgroup within such publications are those based on vehicle-track models simulation, which use dynamical approach, but not the traditional engineering one, to search for proper, best or even optimum shape of TCs.…”

In this paper recent simulation results aimed at studying nonlinear phenomena that accompany motion of railway vehicle in transition curve at velocities around the vehicle critical velocity are presented by the authors. Such results concern six different objects representing railway vehicles. These are: three 2-axle railway bogies, two 2-axle railway cars, and 4-axle railway car. The paper attention is devoted to presenting as many different nonlinear behaviours of the studied objects as possible. This is done first of all to give an idea to the readers of great number of the nonlinear behaviour types that can appear for railway vehicles in transition curves at velocities lower and bigger than vehicle critical velocity. The differences arising from specificity of particular objects are highlighted while systematic variation of the system parameters in order to study influence of such variation on differences in the behaviour is less represented. The paper ends with the comprehensive comments by the authors to the results obtained.
