  1. 21. Analysis and vibration improvements of a forwarder seat

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Xuan Sun; [2012]
    Keywords : ;

    Abstract : I skogsbruket är både förare och fordon utsatta för höga vibrationsnivåer. Stolen i dagens skotare är en av de viktigaste delarna för att kunna isolera föraren från helkroppsvibrationer (WBV). Idag är de flesta stolarna tillverkade utifrån lastbilskrav. READ MORE

  3. 22. 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

  4. 23. U-RANS Simulation of fluid forces exerted upon an oscillating tube array

    University essay from KTH/Farkost och flyg; KTH/Aeroakustik

    Author : Lise Divaret; [2011]
    Keywords : Fluid-structure interaction; CFD; Forces; added mass; drag coefficient; Morison expansion; Unsteady Reynolds Averaged Navier Stokes simulations; Arbitrary Lagrange Euler model.;

    Abstract : The aim of this master thesis is to characterize the fluid forces applied to a fuel assembly inthe core of a nuclear power plant in case of seism. The forces are studied with a simplifiedtwo-dimensional model constituted of an array of 3 by 3 infinite cylinders oscillating in aclosed box. READ MORE

  5. 24. Investigation of Fast High Voltage PDC Measurement based on a Vacuum Reed-switch

    University essay from KTH/Elektroteknisk teori och konstruktion

    Author : Zeeshan Talib; [2011]
    Keywords : step voltage; polarization and depolarization current; vacuum reed switch.;

    Abstract : The diagnostic technique, polarization and depolarization current (PDC) is useful for insulation testing. It requires applying a DC step voltage to the test sample and measuring the current. To measure fast PDC phenomena a fast step is needed. One way of applying a fast high voltage step is to use power electronic switches. READ MORE

  6. 25. Determining the pressure distribution on submerged 2D bodies using dissipative potential flow.

    University essay from KTH/Marina system

    Author : Mirjam Fürth; [2011]
    Keywords : ;

    Abstract : Globalization is reaching the furthest corners of the world and with globalizations comes a rising demand on transportation. In shipping; a significant cost both to the ship owners and the environment are the fossil fuels used for propulsion, even a small reduction in the wave resistance can bring considerable reductions both in operating costs and emissions for such ships.
