  1. 16. Toward the study of combustion instabilities in aircraft engines

    University essay from KTH/Aerodynamik

    Author : Adrien Chatelier; [2014]
    Keywords : ;

    Abstract : The prediction of combustion instabilities is crucial for aircraft engines manufacturers to ensure the reliability and the life span of their engines. To study these phenomena, numerical simulations are more and more often performed. READ MORE

  3. 17. Influence of the ballast on the dynamic properties of a truss railway bridge

    University essay from KTH/Bro- och stålbyggnad

    Author : Lucie Bornet; [2013]
    Keywords : Ballast; Railway bridges; Experimental dynamics; Finite element modelling; Natural frequencies; Eigenmodes; Bridge stiffness.;

    Abstract : To deal with a rapid development of high-speed trains and high-speed railways, constant improvement of the railway infrastructure is necessary and engineers are continuously facing challenges in order to design efficient and optimized structures. Nowadays, more and more railway bridges are built and thus, they require the engineers’ attention both regarding their design and their maintenance. READ MORE

  4. 18. Earthquake Analysis of Pipe Supports in Nuclear Power Plants

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Väg- och vattenbyggnad (CI)

    Author : Johan Mattsson; [2012]
    Keywords : structural analysis; earthquake engineering; mechanics; time history; spectrum; Abaqus; Pipestress; nuclear plant; pipe support; Technology and Engineering;

    Abstract : This is the resulting rapport from a master thesis in the field of structural analysis, with a focus on earthquake engineering. In this project are pipe supports’ impacts on seismic design analysed. This is done by modelling a building, pipe supports and a pipe system in two different computer softwares. READ MORE

  5. 19. Single and double clamped resonator sensors - Design, fabrication and testing

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Muhammad Islam; [2012]
    Keywords : ;

    Abstract : Micro- and nanomechanical single and double clamped resonators are widely being used as mass and temperature sensors due to their high sensitivity, as bio sensors due to their real time label-free detection ability. These resonators have attracted considerable interest from applications like point of care diagnostics, homeland security and environmental monitoring in recent years. READ MORE

  6. 20. Model correlation of an articulated hauler frame

    University essay from Institutionen för teknik, TEK

    Author : Paulina Lundgren; Mohammed Harbe Husein; [2010]
    Keywords : Mode shape; Finite Element; Eigenvalue; vibration; deformation; MAC;

    Abstract : This master thesis has been carried out on behalf of Volvo Construction Equipment. A front frame of an articulated hauler should be analysed according to the Finite Element Method and vibration tests should be made. The results from the experimental tests should be correlated with the analytical test results here using MAC-values. READ MORE
