Introduction of Bezgin-Kolukırık Equations to estimate peak dynamic impact forces caused by wheel flats: Nov. 3 11:00 PST / 14:00 EST / 19:00 GMT / 21:00 EET
Bezgin – Kolukırık Equations (K’B3, and K’B3,H) estimate the maximum values of dynamic impact forces that occur on railway tracks because of wheel flats. These equations explicitly take into consideration the train speed, wheel diameter, wheel flat length, track stiffness, primary wheel spring stiffness, secondary bogie spring stiffness, static wheel force and the Hertzian contact deformation length and estimate the maximum dynamic impact force factors due to wheel flats. K’B3, and K’B3,H provide their beneficiary with practical tools that one can rapidly use to have an understanding of the extent of the forces that occur because of wheel flats. One can make use of this understanding, before one resorts to or judges the need to resort to higher order numerical analysis methods to evaluate the interaction of a wheel with a flat with the railhead. This presentation will introduce the Bezgin – Kolukırık Equations and present their applications for various wheel flat-rail interaction cases. This presentation will also introduce a worksheet titled ALLTRACK v1 that rests on the principles of the Bezgin Method, which was used to develop K’B3, and K’B3,H.

Donald Julius Groen Prize Lecture: Dec. 4 12:00 GMT
We are very proud to let you know that one of our colleagues, Dr. Roger Lewis of Sheffield University, has been awarded the Donald Julius Groen Prize in Tribology this year. Sponsored by IMechE, it is “Awarded for outstanding papers or for outstanding achievements in the sphere of” Tribology.
Roger will be giving a lecture on “The Wheel/Rail Interface: Understanding and Controlling the Complex Tribology of an Open System” on the 4th of December at 12pm. You are all invited to register and attend this free lecture – see https://events.imeche.org/ViewEvent?code=TLE7210
Please join us in congratulating Roger for this well-deserved recognition.
