Special Issue Information

Dear Colleagues,

Proper operations of railway transportation systems during both braking and traction maneuvers require adequate values of the adhesion coefficient, but contaminants can strongly affect the shape of the adhesion curve as a function of the contact creepage. Hence, a deep knowledge of adhesion behavior under different conditions is essential to optimize the dynamic behavior of railway vehicles and to define efficient and reliable algorithms for on-board mechatronic devices and control strategies for adjusting the traction/braking torque, e.g., wheel slide protection (WSP) and antiskid systems.

This Special Issue calls for papers dealing with advanced and innovative aspects regarding the experimental investigation, the realtime estimation, the numerical modeling, and the optimization of the wheel–rail adhesion coefficient. In view of the widespread applications of digital twins, this Special Issue also welcomes works regarding machine learning techniques.

In this paper, we present a method of calculating cornering stiffness for different camber angles. The method removes the need for measurement data at different camber angles. The camber angle is regarded as equivalent to a local shift of load in the contact patch from one half-side to the other. A simple model is presented to describe the load shift. The cornering stiffness from each side, accounting for their loads, is then assumed to contribute to the total stiffness. The load shift model is validated through two finite element models. Cornering stiffnesses given by the model for two different tires are then compared to the measurements. To show the universality of the method, its application to interpolated measurement data is shown. The proposed method shows promising results for moderate camber angles. Full article
