  1. 1. Towards adaptive bogie design

    Författare :Milad Mousavi Bideleh Seyed; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sensitivity analysis; Optimization; suspension system; bogie; active control;

    Sammanfattning : Suspension components play a crucial role in bogie dynamics behavior. In this regard, passive and active systems are developed to meet various design requirements. Adaptive suspension systems can adjust the bogie dynamics with respect to different operational scenarios and as a result improve the vehicle performance. LÄS MER

    Sammanfattning : Railways provide fast, safe, clean, and cheap transportation service. The cost efficiency inrailway operations can be scrutinized from different perspectives. LÄS MER

  4. 3. Multi-objective optimization of railway bogie suspension damping

    Författare :Albin Johnsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railway vehicle dynamics; Bogie suspension design; Multi-objective optimization; Pareto optimized bogie primary and secondary suspensions damping;

    Sammanfattning : In this thesis multi-objective optimization is used to find Pareto fronts showing the set of optimized damping parameters of primary and secondary bogie suspensions. Special interests are put on requirements to enhance safety and comfort of a railway vehicle. LÄS MER

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

    Författare :Dan Brabie; Evert Andersson; Roderick A Smith; KTH; []
    Nyckelord :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;

    Sammanfattning : 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.

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

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

    Sammanfattning : 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.
