2. 1. Multi-Functional Composite Design Concepts for Rail Vehicle Car Bodies

   Author : David Wennberg; Sebastian Stichel; Per Wennhage; Thilo Bein; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Car body; Composite; Finite element; Lightweight; Multi-discipline; Multi-functional; Optimisation; Rail Vehicles; Sandwich Panels;

   Abstract : Structures and material combinations, tailored for multiple purposes, are within the reach of vehicle manufacturers. Besides reducing the environmental impact of the transportation sector these multi-functional structures can reduce costs, such as development, manufacturing and maintenance, and at the same time offer improved comfort to the passengers.

4. 2. On Derailment-Worthiness in Rail Vehicle Design : Analysis of vehicle features influencing derailment processes and consequences

   Author : Dan Brabie; Evert Andersson; Roderick A Smith; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; derailment; bogie design; wheel-sleeper impact; simulation; deviation; vehicle inter-connection; guidance mechanism; substitute guidance; articulated train; railway safety; Vehicle engineering; Farkostteknik;

   Abstract : This thesis aims at systematically studying the possibilities of minimizing devastating consequences of high-speed rail vehicle derailments by appropriate measures and features in the train design including the running gear. Firstly, an empirical database is established containing as much relevant information as possible of past incidents and accidents that have occurred at substantial running speeds due to mechanical failure close to the interface between the running gear and the track.

5. 3. On the Influence of Rail Vehicle Parameters on the Derailment Process and its Consequences

   Author : Dan Brabie; Evert Andersson; Johan Oscarsson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; train; railway; rail vehicle; accident; incident; derailment; bogie design; simulation; wheel; sleeper; impact; Vehicle engineering; Farkostteknik;

   Abstract : This thesis aims at systematically studying the possibilities of minimising devastatingconsequences of high-speed derailments by appropriate measures and features in thetrain design, including the running gear. The course of events immediately afterderailments is studied with respect to whether the train stays upright and close to thetrack centre line or deviates laterally with probably serious consequences.
