    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High-speed railway bridges; Bridge dynamics; Running safety; Passenger comfort; Structural reliability; Meta-models; Surrogate models; Adaptive sampling; Reliability-based design optimization; Höghastighetsjärnvägsbroar; Brodynamik; Trafiksäkerhet; Passagerarkomfort; Konstruktioners tillförlitlighet; Metamodeller; Surrogatmodeller; Adaptiv sampling; Tillförlitlighetsbaserad designoptimering; Structural Engineering and Bridges; Bro- och stålbyggnad;

    Sammanfattning : Increasing the operational speed of trains has attracted a lot of interest in the last decades and has brought new challenges, especially in terms of infrastructure design methodology, as it may induce excessive vibrations. Such demands can damage bridges, which in turn increases maintenance costs, endangers the safety of passing trains and disrupts passenger comfort. LÄS MER

  5. 4. Some Aspects of Wear and Structural Dynamics

    Författare :Jakob Knudsen; Hållfasthetslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration and acoustic engineering; Mechanical engineering; hydraulics; chaos; interfacial breakdown; stability; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik; vacuum technology; fretting wear; fretting map; vibro-impact dynamics;

    Sammanfattning : The topic of this thesis is dynamics and wear of structures. In the six appended papers different aspects of wear and dynamics of a model system are studied. The considered system consists of a long slender rod with unilateral supports, subject to harmonic and stochastic excitation. LÄS MER

  7. 5. Application-level Chaos Engineering

    Författare :Long Zhang; Martin Monperrus; Benoit Baudry; Leon Moonen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fault injection; dynamic analysis; software resilience; chaos engineering; Datalogi; Computer Science;

    Sammanfattning : With the development of software techniques, software systems nowadays are becoming highly complex. In order to keep such systems as reliable as possible, developers need to design various error-handling mechanisms. LÄS MER
