  1. 1. Optimizing the functionalities of a code for real time dynamics of finite systems

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Yasser Mahfoud; [2018]
    Keywords : Physics and Astronomy;

    Abstract : The many-body problem in quantum mechanics always presents new challenges and ways to discover new properties of existing materials. The difficulty (if not the impossibility) to solve the many-body problem analytically makes the numerical methods an appealing approach. READ MORE

  2. 2. Finite Element Analysis of the Dynamic Effect of Soil-Structure Interaction of Portal Frame Bridges - A Parametric Study

    University essay from KTH/Bro- och stålbyggnad; KTH/Bro- och stålbyggnad

    Author : Turgay Dagdelen; Shaho Ruhani; [2018]
    Keywords : Soil-Structure Interaction; Railway Bridge; Portal Frame Bridge; Dynamic Analysis; Parametric Study; Nonlinear Analysis; Jord-struktur interaktion; Järnvägsbro; Plattrambro; Dynamisk analys; Parametrisk studie; Icke-linjär analys;

    Abstract : In Sweden, the railway sector currently faces the challenge of developing its first high-speed railway line, in response to the need to provide faster domestic and international transport alternatives. High-speed train passages on railway bridges can cause resonance in the bridge superstructure, which induce high accelerations that should not exceed the limits stipulated in the current design code.

  3. 3. Train Induced Vibration Analysis of an End-frame Bridge : Numerical Analysis on Sidensjövägen

    University essay from KTH/Bro- och stålbyggnad; KTH/Bro- och stålbyggnad

    Author : Niklas Wiberg; Jasmin Halilovic; [2018]
    Keywords : Accelerations; Dynamics; End-frame bridge; FE-modeling; Frequency response function; High-speed railway; Soil structure interaction; Train induced vibrations; 2D 3D;

    Abstract : Higher speeds and higher capacity will cause the Swedish rail network to be exposed to disturbing dynamic effects. Higher speeds cause higher vertical acceleration levels of the bridge deck. In this thesis, a numerical analysis of a three span end-frame bridge subjected to train induced vibrations is performed.

  4. 4. 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

  5. 5. Ocean Waves Estimation : An Artificial Intelligence Approach

    University essay from Mälardalens högskola/Akademin för innovation, design och teknik

    Author : Andreas Ramberg; [2017]
    Keywords : Artificial Intelligence; Case-Based Reasoning; Encounter Angle; Encounter Spectrum; Feedforward Neural Network; Genetic Algorithm; Inverse Problem; Marine Vessels; Master Thesis; MATLAB; Model Parameter Estimation; Ocean Theory; Peak Period; Response Amplitude Operator; Ships; Significant Wave Height; Transfer Function; Wave Spectrum; Waves;

    Abstract : This thesis aims to solve the mathematical inverse problem of characterizing sea waves based on the responses obtained from a marine vessel sailing under certain sea conditions. By researching this problem the thesis contributes to the marine industry by improving products that are using ocean behavior for controlling ship's dynamics. READ MORE
