Towards the end of our trip through Asia, Parham and I had the great opportunity to visit a Korail depot for Heavy Maintenance of KTX high speed trains. Very impressive work was going on there, the lifecycle behaviour of the components differs quite a bit from Europe.


In the afternoon we gave a talk on PHM for railways form both US and European perspective to Scientists and Students at the Korean Aerospace University following an invitation from Professor Choi. 

Today I had the honor to present Parhams, Manfreds and my paper on how to apply Condition Based Maintenance in an economic fashion. Especially in our highly competitive railway environment, it is vital to think of the business case from the very beginning – just as we did in the concept of Wagon 4.0.

The current developments in Big Data and Machine Learning will provide exciting opportunities to improve the quality of service, the safety and the performance in freight rail – and perhaps the easiest way to abolish freight rail is not to make full use of these!

The slides and the paper are available for download – I look forward for your comments.

My second presentation at ICRT conference shows the preliminary results of the research project with Nowe investigating the effect of sanding on the wheel-rail adhesion area.

Preliminary results show that it is possible to model the increase in adhesion area quite well. For details, refer to the slides available here.

I am presenting our ideas on the connected wagon at the First International Conference on Rail Transportation in Chengdu. My first observation is that rail freight and especially heavy haul is well represented, so perhaps my slides (available here) are well received.

Miao hat den Lichtraumnachweis nach BOStrab und der chinesischen Norm für Metro-Fahrzeuge verglichen sowie ein Excel-Tool zur Berechnung implementiert.


Die praxisnahe Arbeit wurde in Zusammenarbeit mit Prose München durchgeführt und dort von Dr. Kurzeck betreut – vielen Dank!

Mit dieser Frage hat sich Martin Schöppner in seiner Bachelorarbeit auseinandergesetzt. Besonders spannend fand ich die Einbeziehung der Anforderungen aus den TSI und die Berücksichtigung von ECM – herzlichen Glückwunsch, Martin!

Martin hat seine Arbeit bei der DB Fahrzeuginstandhaltung in Krefeld erstellt – da ist man um ein Fahrzeug für den Hintergrund nicht verlegen!

Today I represent FH Aachen’s research at the IMechE Stephenson Conference 2017 – with an overview of Wagon 4.0. The spirits are really enthusiastic, so this optimistic view on the future of rail freight appears to be quite right.

The full slides are here: 170403Wagon40.

Today I gave a presentation on the potential for use of acceleration data to obtain braking curves and their uncertainty. This may prove especially useful for freight trains, however it can be used on any type of train.

For those interested in more detail, the slides are here. More technical details will be provided in my paper for the Asia Pacific conference of Prognostics and Health Management society in July!

Nach den üblichen „wird beim Kunden“-montiert Aktionen haben wir es doch tatsächlich geschafft, unsere Parkbahn-Lokomotive für die Railway Challenge auf dem HIT der FH Aachen zu präsentieren – natürlich noch leer…

Für Studieninteressierte: hier die Prezi der Informationsveranstaltung

#RAILWAYCHALLENGE

Amir hat heute seine Bachelorarbeit zu Thema Rad-Schiene-Kontakt unter Berücksichtigung von reibwertverbessernden Mitteln abgeschlossen. Herausragend ist dabei, dass Amirs Ergebnisse die Grundlage für unser Paper für die Rad-Schiene in Dresden 2017 sind – wir freuen uns! Weitere Veröffentlichungen sind geplant.
