2. 1. A System-of-Systems Approach for Enhancing Asset Management of Railway System

   Author : Jaya Kumari; Ramin Karim; Adithya Thaduri; Pierre Dersin; Miguel Castaño Arranz; Mirka Kans; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; railways rolling stock; system-of-systems; asset management; maintenance; fleet management; industrial AI; digitalisation; Operation and Maintenance Engineering; Drift och underhållsteknik;

   Abstract : In Sweden, railway transport of freight and passengers is a significant portion of the total transport system. The demand for railway transport is forecasted to increase in the coming decades. One of the main reasons for this ever-increasing demand is the requirement for sustainable transport, nationally and globally. READ MORE

4. 2. Modelling and laboratory investigations on freight wagon link suspensions with respect to vehicle-track dynamic interaction

   Author : Per-Anders Jönsson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; railway; freight wagon; running gear; link suspension; laboratory test; ; Other engineering mechanics; Övrig teknisk mekanik;

   Abstract : The link suspension is the most prevailing suspension system for freight wagons in central and western Europe. The system design is simple and has existed for more than 100 years. However, still its characteristics are not fully understood. READ MORE

5. 3. Dynamic Vehicle-Track Interaction of European Standard Freight Wagons with Link Suspension

   Author : Per-Anders Jönsson; Sebastian Stichel; Evert Andersson; Jerzy Piotrowski; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; railway; freight wagon; running gear; link suspension; laboratory test; ; stiffness; dry friction; hysteresis; simulation; vehicle-track interaction; multibody; simulation; MBS; Vehicle engineering; Farkostteknik;

   Abstract : The link suspension is the most prevailing suspension system for freight wagons in Central and Western Europe. The system design is simple and has existed for more than 100 years. However, still its characteristics are not fully understood. READ MORE

6. 4. Coordination of Heavy-Duty Vehicle Platooning

   Author : Sebastian van de Hoef; Dimos V. Dimarogonas; Simona Sacone; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; road freight transport; optimization; optimal control; automatic control; fuel-efficiency; match-making; off-board; intelligent transport systems; automated driving; clustering; scheduling; cooperative; large-scale; dynamic programming; trucks; Electrical Engineering; Elektro- och systemteknik;

   Abstract : A network-wide coordination system for heavy-duty vehicle platooning with the purpose of reducing fuel consumption is developed. Road freight is by far the dominating mode for overland transport with over 60 % modal share in the OECD countries and is thus critically important for the economy.

7. 5. Curving performance and nonlinear dynamic behaviour of freight cars with three-piece bogies

   Author : Ansel Berghuvud; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

   Abstract : This thesis considers modelling and simulation of the dynamic interaction between freight cars and railway track. The aim of the work is to study and enhance the knowledge and understanding of the nonlinear interaction for different heavy haul freight vehicle concepts of ore wagons applied at Malmbanan/Ofotbanen in northern Sweden and Norway.
