  1. 11. Method Development and Analysis of Tensile Stresses in Windscreens : A study on the dynamic stresses on windscreens subjected to random vibrations.

    Master-uppsats, Högskolan i Jönköping/Tekniska Högskolan

    Författare :Philip Reis; Karthik Murthy; [2018]
    Nyckelord :Dynamic Stresses; FE Method; Laminated Glass; Modal Analysis; Random Vibration; Windscreens;

    Sammanfattning : The thesis work deals with the study and determination of static and dynamic stresses acting on windscreen structures during transportation from the manufacturing site to the production plant. To simulate the stress distribution affected by the transportation, a finite element model of the windscreen is development of the structure and tested. LÄS MER

  3. 12. Equipment for Accelerated Vibration Testing

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Daniel Hideblad; [2017]
    Nyckelord :Accelerated vibration testing equipment; vibration equipment; shock; eee-components; accelerated vibration testing; HALT; HASS; Electrodynamic; shaker;

    Sammanfattning : The increasing complexity with the decrease in size of EEE – components (Electronic, electric and electromagnetic) raises the question on how higher energy frequencies will affect the components and their continuous development. The most common vibration testing equipment currently in use within the automotive industry and SCANIA CV AB are the electrodynamic shaker (ED system). LÄS MER

  4. 13. Stress simulation of the SEAM CubeSat structure during launch.

    Magister-uppsats, KTH/Hållfasthetslära (Inst.)

    Författare :Julie Fagerudd; [2015]
    Nyckelord :;

    Sammanfattning : A spacecraft is subjected to dynamic and static loads during launch. These loads are deterministic and of random nature and cannot be tested under the real conditions due to cost considerations. LÄS MER

  5. 14. Quantification and Implementation of Structural Damping in MBS Flexible Bodies

    Master-uppsats, Lunds universitet/Mekanik

    Författare :Anton Flink; [2015]
    Nyckelord :Technology and Engineering;

    Sammanfattning : In multi body simulation (MBS) using flexible bodies, damping is an important model input to be able to predict the response of a structure with sufficient precision. The purpose of this thesis has been to estimate the structural damping of an experimental setup and implement the estimated damping into MBS-models of the setup. LÄS MER

  7. 15. Methods to Predict Structural Response due to Random Sound Pressure Fields

    Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära; Linköpings universitet/Tekniska fakulteten

    Författare :Pontus Gunnarsson; [2015]
    Nyckelord :;

    Sammanfattning : To predict structural responses due to random sound pressure fields are of great interest within many fields of aircraft development, particularly within acoustic fatigue problems and definition of vibration requirements.  Today there exist some methods to quantify sound pressure fields affecting the air-fighters.
