The wheel-rail contact modeling problem assumes a preponderant role on the dynamic
analysis of railway systems using multibody systems formulations. The accurate and efficient …

A wheel–rail contact formulation for analyzing the nonlinear train–structure interaction that
takes into account the wheel and rail geometry is proposed. While most of the existing …

The development of wheel–rail contact models is an active topic of railway research with the
dual objective of improving the accuracy of multibody simulations and reducing its …

An enhancement in the wheel–rail contact model used in a nonlinear vehicle–structure
interaction (VSI) methodology for railway applications is presented, in which the detection of …

In the research of the wheelset's hunting oscillation, it is found that if the wheel–rail
geometric contact is nonlinear, the wheelset oscillation will produce the high-order odd …

The effects of bogie primary and secondary suspension stiffness and damping components
on the dynamics behavior of a high speed train are scrutinized based on the multiplicative …

Bearing effects have not been deeply investigated in the dynamic analysis of a train–bridge
coupled system subjected to earthquake motions, and existing studies on base isolation of …

This paper considers a three-axle railway locomotive bogie running on a straight track and
presents pattern diversity and bifurcation characteristics of its hunting behaviors at forward …

The wheelset on a railway vehicle experiences the problem of hunting motion, the onset of
which occurs when travelling above the associated critical speed. This is known as a flutter …

This paper proposes a data-driven approach for faultdetection and isolation of bogie
suspension components with on-board acoustic sensors. The fault detection technique is …
