Summary: The paper provides a review of modelling approaches for conformal wheel/rail rolling contact in the context of railway vehicle dynamics simulation. The complexity of conformal wheel/rail contact conditions compared to nonconformal ones is highlighted, along with the trade-off between accuracy and computational efficiency. The paper also proposes challenges and future research directions in this field.

Summary: This research proposes a new semi-analytical boundary element method to determine the wheel-rail contact zone and the normal stress distribution within it. The method uses strip elements to discretize the potential contact area, and employs an iterative algorithm to satisfy the contact constraints. The approach provides a good approximation of the pressure distribution and enables fast computation speeds, making it suitable for non-elliptic cases in railway dynamics.

Summary: This paper provides an overview of different theories, including exact formulation, simplified models and a recent two-regime model, to analyze unsteady rolling contact phenomena between wheel and rail. The classic solution to the transient problem and the more complicated situation of combined creepages and spin using simplified models are discussed. Analytical solutions and qualitative results for time-varying and constant creepages are reported. Finally, a novel theory using ordinary differential equations is introduced to describe the transient evolution of force-creepage characteristics.

Summary: A transient wheel-rail rolling contact model and a vehicle-track coupled dynamics model were developed to calculate normal wheel-rail interactions at high frequencies in elasticity. The results of 180 cases showed significant differences in contact forces predicted by the CD model compared to the RC model, indicating the important role of ignored structural and wheel-rail flexibilities in high-frequency interactions. A modified non-linear Hertzian spring was developed to improve the accuracy of the CD model with reference to the RC predictions, providing insights for determination of contact spring and contact filter effect at high frequencies.

Summary: With the increase in computational capacity, linear models have been replaced by non-linear formulations in wheel/rail tangential contact. However, linear formulations are still necessary for certain applications such as acoustic problem modeling. This work presents a new theory of unsteady linear tangential rolling contact for non-Hertzian areas, based on the Variational Theory, which allows for a more efficient and accurate solution to the contact problem.

Summary: This paper compares the application of beam and continuum finite element models in wheel-rail impact problems, revealing differences through time-frequency analysis and parameter evaluation. Results show performance disparities between the two models at specific frequencies, and comparison with field observations demonstrates the greater accuracy of the continuum finite element model.

Summary: Wear in the wheel-rail contact has a significant impact on the railway system, depending on the contact area's location and stresses. Some wheel and rail profiles are sensitive to small changes in relative kinematics, which can be caused by displacements or structural deformations. This paper presents a refined model exploring the impact of structural deformations on the wheel-rail contact.

Summary: This paper focuses on the research of LM&CHN60 wheel and rail profiles commonly used in Chinese metro, proposing an optimization method for rail profiles based on worn and unworn profiles to improve vehicle stability and minimize rail wear. The application of optimized rail profiles significantly reduces the growth rate of rail wear, doubling the maintenance intervals for rail reprofiling.

Summary: Modeling wheel-rail interaction at short-wave irregularities is essential for analyzing and preventing severe impact. This study broadens the applicability of vehicle-track dynamics model to account for 3D short-wave irregularities on rail surface, providing global dynamics and local contact solutions. The results highlight the role of short-pitch rail corrugation in dynamic wheel-rail interaction, specifically in wheel center trajectory and time-varying contact stiffness.

Summary: The study found that increasing the wave depth leads to increases in the average values of rail/wheel vertical vibration acceleration and longitudinal creepage/creep force, while decreasing the average value of transverse creepage/creep force. On the other hand, increasing the wavelength decreases the average values of rail/wheel vertical vibration acceleration and longitudinal creepage/creep force, while increasing the average value of transverse creepage/creep force.

Summary: This paper investigates the hunting oscillation of the wheelset and finds that if the wheel-rail contact is nonlinear, high-order odd harmonic frequencies (HOHFs) are generated in addition to the hunting fundamental frequency. A kinematics model of a wheel-rail nonlinear geometric contact system is established, and it is proven that only odd harmonics exist in the hunting oscillation. Numerical simulations show that the HOHFs can produce lateral vibration responses in the bogie frame, and track irregularity and primary suspension can influence or suppress the vibration response of the HOHFs.

Summary: This investigation integrates a fully-parameterized approximation of nonlinear wheel/rail interaction into a simplified vehicle model and conducts a Hopf bifurcation analysis to reveal the influence of wheel/rail contact geometry and secondary suspension parameters for high-speed rail vehicles. The results show that the nonlinear vehicle model can meet the simulation requirements for both carbody hunting and bogie hunting, while the linear vehicle model may bring errors.
