  1. 11. Simulation and experimental study for vibration analysis on rotating machinery

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Mohd Shafiq Sharhan bin Zainal; [2020]
    Keywords : Multi Degree of Freedom MDOF ; Rotating machinery; Single Degree of Freedom SDOF ; Unbalance; Vibration analysis;

    Abstract : This student thesis aims to analyze the unbalance on rotating machinery by simulation and experimental. The machinery flywheel rotation is modelled as a Single Degree of Freedom (SDOF) and Multi Degree of Freedom (MDOF) system. The model rotation unbalance is simulated by MATLAB. Then the vibration measurement is taken by experimental. READ MORE

  3. 12. Dynamic Analysis of an Automotive Power Transfer unit : Towards prediction of TE and housing vibrations

    University essay from KTH/Maskinkonstruktion (Avd.)

    Author : Nikhil Maharshi Kosaraju; [2019]
    Keywords : Power transfer unit PTU ; Multi-Body Simulation MBS ; Transmission Error; Gear NoiseVibration; Modal Analysis; Vinkelväxlen PTU ; Multi-Body Simulering MBS ; transmissionsfel TE ; Växelljud och vibrationer; Modal analys;

    Abstract : This work describes the use of Multi-Body Simulation (MBS) to create a virtual prototype of a geared drive called Power transfer unit (PTU). PTU is a subsystem of the all-wheel drive driveline responsible for transfer of power between front and rear axles in an Automobile. READ MORE

  4. 13. Noise Analysis of Computer Chassis and Secondary Sound Source Noise Reduction

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Haosheng Zheng; Kaichun Zhang; [2019]
    Keywords : Computer; Acoustic FEM; LMS Virtual. Lab; Acoustic-Vibration Coupling;

    Abstract : This article focuses on computer noise analysis and noise reduction processing. With the popularity of computers, people are increasingly demanding the comfort of using computers. Solving the noise problem of the computer case can make the working environment more comfortable. READ MORE

  5. 14. Semi-active suspension seats in High speed crafts

    University essay from KTH/Marina system

    Author : Victor Ekström; [2019]
    Keywords : ;

    Abstract : The working environment of a high-speed-craft (HSC) can be uncomfortable and hazardous for the crew and passengers on board. This due to the repeated exposure to high levels of vibration and shocks, that can lead to reduced performance and severe injuries to the back and neck. READ MORE

  6. 15. Railway bridges with floating slab track systems : Numerical modelling of rail stresses - Dependence on properties of floating slab mats

    University essay from Luleå tekniska universitet/Byggkonstruktion och -produktion

    Author : Daniel Kostet; [2018]
    Keywords : ballasted track; bridge; elastic mat; expansion; finite element method FEM ; finite element analysis FEA ; floating slab mat; interaction; International union of railways UIC ; non-ballasted track; SOFiSTiK; ballasterat spår; ballastfritt spår; bro; dilatationsfogar; finita elementmetoden FEM ; finit elementanalys FEA ; fixerat spår; interaktion; Internationella järnvägsunionen UIC ; SOFiSTiK; vibrationer; vibrationsdämpande matta;

    Abstract : The increased use of continuously welded rails in the railway systems makes it necessary to increase the control of the rail stresses to avoid instability and damages of the rails. Large stresses are especially prone to appear at discontinuities in the railway systems, such as bridges, due to the interaction between the track and the bridge. READ MORE
