    Sammanfattning : One way to tackle the climate change society is facing today is through the change to renewable energy sources, such as wind power. Today, a trend when it comes to technology is that products are evolving into becoming more cyber-physical systems (CPS) by integrating functions realized with mechanics, control and communication.

  2. 2. Monitoring and Modelling of the Abiskojåkka Bridge

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Byggkonstruktion och brand

    Författare :Kasper Furenstam; [2020]
    Nyckelord :Prestressed bridge; Abisko; Monitoring; thermal effects; FEM;

    Sammanfattning : The infrastructure of today is getting older and problems caused by deterioration over time is affecting the service life of these structures. In Sweden most of the existing bridges were constructed 60 to 70 years ago, rising the need to determine the state of health of the bridges as the maintenance costs will increase heavily. LÄS MER

  4. 4. Development of Damage Tolerance Methodology for Antenna Installations in Pressurized Aircraft

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Jens Fagerberg; [2020]
    Nyckelord :;

    Sammanfattning : Modifying an aircraft must be done in a safe way such that the safe operation of the aircraft is not violated. Compliance must be shown towards certification and airworthiness regulations in order to install a modification and allow for commercial flight. Certification is a time-consuming process where damage tolerance analysis is a major part. LÄS MER

  5. 5. Influence of matrix and alloying on the high cycle fatigue properties of compacted graphite iron for cylinder heads

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Erik From; [2020]
    Nyckelord :;

    Sammanfattning : Continued improvements in combustion processes, introduction of biofuels, decreasing fuel consumption and increasing specific power will inevitably lead to an increase of the combustion pressure, which can be accompanied with a temperature increase. This will increase the loading on many components and drives the development of materials more resistant to the harsh conditions close to the engine. LÄS MER
