  1. 6. The Effect of High Wheel Impact Load on the Rail Reliability - a Case Study at Bodsjön

    University essay from KTH/Spårfordon

    Author : Ngoc Thúy Vy Dang; [2021]
    Keywords : rail defects; rail reliability; Ultrasonic Test; wheel damage; Wheel Impact Load Detector; statistics; järnvägsdefekter; järnvägssäkerhet; ultraljudstest; hjulskador; hjullastningsdetektor; statistik;

    Abstract : This study focuses on the reliability of railway track in the relation with high loads resulted from wheel damages, where higher (dynamic) vertical wheel loads are expected from trains with damaged wheels. The Swedish Transport Administration (Trafikverket) has monitored and recorded data of rail defects and breaks. READ MORE

  3. 7. Influence of load distribution on trough bridges

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Jacob Gustafsson; [2021]
    Keywords : Bridge; Trough bridge; Concrete; Load distribution; Ballast;

    Abstract : There are approximately 4000 railway bridges in Sweden and a common construction type is the short span concrete trough bridge. With the current standards the load distribution through ballast is assumed to be uniformly distributed with a distribution slope of 2:1 according to the Swedish Administration of Transport or 4:1 according to Eurocode 1.

  4. 8. Paratransit and Bus Rapid Transit Interaction Approaches and Corresponding Barriers

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Messner Laura; [2020]
    Keywords : informal public transport; multi-regimes; socio-technical transition theory; stakeholder theory; Sub- Saharan Africa; sustainable development;

    Abstract : Public transport in many Sub-Saharan African cities consists of paratransit, mini-to-medium-sized buses, which provide public transport and operate demand-driven and unscheduled. This form of public transport is often seen as less safe, less dependable, and environmentally unfriendly. READ MORE

  5. 9. Pressurizing of high-pressure fuel system forsingle cylinder test cell

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Gustaf Glaad; [2019]
    Keywords : Alternative fuels; Ultra high-pressure fuel system; Common rail direct injection fuel system; Diesel-like fuels; Compression ignited fuels;

    Abstract : This master thesis covers the development of a high-pressure fuel system for compression ignitedfuels such as diesel and diesel-like fuels that will be deployed into a single cylinder test cell at AVLMTC Södertälje, Sweden. The test cell is used by AVL to conduct research and testing of new fuelsfor their customers and this new fuel system will widen the span of fuels able to be tested by theequipment. READ MORE

  6. 10. Modelling of high-pressure fuel system for controller development

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Eric Pettersson; [2019]
    Keywords : Common-Rail Direct Injection; fuel system; water hammer; pressure oscillations; physical modelling; state-space representation;

    Abstract : This master thesis treats the modelling of a common-rail direct fuel injection system where pressure generation is decoupled from the injection process. It has been shown that the fuel pressure plays a vital role for the general performance of the engine, affecting both emissions and efficiency, and it is carefully regulated to achieve optimal performance at different operating points.
