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

    University essay from Högskolan i Jönköping/Tekniska Högskolan

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

    Abstract : 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. READ MORE

  3. 17. Parameter study of bodywork attachments influencing the chassis dynamics by vibration response analysis

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Anirudh Gururaj Deshpande; [2018]
    Keywords : Eigen frequency; modal analysis; frequency response function; damping; Egenfrekvens; modalanalys; rekvensrespons; dämpning;

    Abstract : Bilindustrin är i ständig utveckling och är väl medvetna om de ökande kraven från kundermed avseende på körkomfort och körupplevelse. Lastbilar med tunga laster är ofta utrustademed en påbyggnad, till exempel en låda för pallar och gods, en sopsamlare eller en stödram förbärning av timmer. READ MORE

  4. 18. Analytic, Simulation and Experimental Analysis of Fluid-Pipe Systems

    University essay from KTH/MWL Marcus Wallenberg Laboratoriet

    Author : Siddharth Venkataraman; [2018]
    Keywords : fluid-structure interaction; modal interaction model; viscosity;

    Abstract : Inviscid fluid inside thin pipe system is first analytically solved for eigenfrequencies and eigenmodes using Modal Interaction Model method with fluid-structure interaction condition at boundary. Shear-diaphragm boundary condition is used for comparing and validating Analytic results with Simulation using COMSOL Multiphysics. READ MORE

  5. 19. Modeling and Simulation of Brake Squeal in Disc Brake Assembly

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Jenny Nilman; [2018]
    Keywords : Brake Squeal; Complex Eigenvalue Analysis; Model Validation; Parametric Study; High Frequency; Brake Noise;

    Abstract : Brake squeal is an old and well-known problem in the vehicle industry and is a frequent source for customer complain. Although, brake squeal is not usually affecting the performance of the brakes, it is still important to address the problem and to predict the brakes tendency to squeal on an early stage in the design process.

  6. 20. Experimental Procedures for Operational Modal Analysis of a Power Pack on a Drill Rig

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : Oscar Nilsson; [2017]
    Keywords : Operational modal analysis; OMA; engine sweep; modal identication; harmonic scaling;

    Abstract : All structures have modal properties such as natural frequencies and damping. In engineeringit is often of interest to estimate these modal properties for certain structures, to be used whenmodelling for example fatigue. This is done by computing them from finite element models, by using experimental measurements or both. READ MORE
