  1. 6. Creating a self-driving terrain vehicle in a simulated environment

    University essay from Umeå universitet/Institutionen för fysik

    Author : Jonas Markgren; [2020]
    Keywords : ;

    Abstract : Outside of the city environment, there are many unstructured and rough environments that are challenging in vehicle navigation tasks. In these environments, vehicle vibrations caused by rough terrain can be harmful for humans. In addition, a human operator can not work around the clock. READ MORE

  3. 7. Attenuation of structure-borne vibrations induced by trains passing railway switches

    University essay from KTH/Marcus Wallenberg Laboratoriet MWL

    Author : Fredrik Lindström; [2020]
    Keywords : ;

    Abstract : The study of structure-borne vibrations caused by railway traffic is becoming increasingly relevant along with the expansions of cities, as building projects are forced towards more sensitive areas, e.g closer to railway tracks. With high enough vibration levels, there is a risk for human annoyance inside buildings. READ MORE

  4. 8. New Measurement Methods For Ground Vibration Test

    University essay from KTH/Flygdynamik

    Author : Hugo Perez; [2020]
    Keywords : ;

    Abstract : Flight-testing represents an important step of an airplane development. Every new or modified aircraft configuration is tested. Through set of tests, the quality and reliability of aircrafts are guaranteed. At Dassault Aviation, the flight test Directorate responsible for carrying out flight tests is located at Istres, in South of France. READ MORE

  5. 9. Energy analysis and cost estimation of a potential On-shore Power Supply system in the Port of Gävle

    University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

    Author : Juan Gutierrez Saenz; [2019]
    Keywords : On shore Power Supply; Alternative Marine Power; High Voltage Shore Connection; Shore side Power; Ship’s emissions; Marine fuel;

    Abstract : The Port of Gävle is one of the most important harbours in Sweden as far as size and freight capacity is concerned. Marine traffic is increasing greatly, thus environmental pollution as well as noise and vibrations are of major concern in port cities. READ MORE

  6. 10. Spatial vibration measurements : operating deflection analysis on the example of a plate compactor

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Adrian Potarowicz; Seyed Mazdak Hosseini Moghadam; [2018]
    Keywords : Reversible Compactor; Mechanical Vibration; Signal Processing; Power Spectrum estimator; Power Spectral Density estimator; Operating Deflection Shape;

    Abstract : The operating motion of a ground compactor uses high power vibrations to improve mechanical properties of a compacted ground. This motion gives a good base for the vibration analysis with an aid of Signal Processing. In this thesis, the motion of a bottom plate in a compactor is of the main interest. READ MORE
