  1. 1. Correlation-based analysis on thin walled tubes

    Master-uppsats, Jönköping University/JTH, Produktionsutveckling

    Författare :Andreas Hedlund; Daniel Blom; [2022]
    Nyckelord :Thin-walled tubes; Crashworthiness; Energy absorption; Finite element method; Finite element method automation.;

    Sammanfattning : In the transportation sector, crash structures are often used to protect their inhabitants inthe event of a collision. These crash structures frequently utilize thin-walled tubes as energyabsorbers. The process of developing thin-walled tubes is iterative based and requires mul-tiple simulations, making it resource intensive. LÄS MER

    Sammanfattning : In the automotive industry there is a conflict between the need for weight reduction in order to reduce the CO2 emissions and the need for high safety. It has led to the use of high strength steel instead of the traditional lightweight materials. LÄS MER

  7. 5. Finite Element based Parametric Studies of a Truck Cab subjected to the Swedish Pendulum Test

    Magister-uppsats, Institutionen för ekonomisk och industriell utveckling

    Författare :Henrik Engström; Jens Raine; [2007]
    Nyckelord :Parametric Studies; Crash Analysis; Metamodel; Monte Carlo Analysis; Robust Design; Stochastic variations;

    Sammanfattning : Scania has a policy to attain a high crashworthiness standard and their trucks have to conform to Swedish cab safety standards. The main objective of this thesis is to clarify which parameter variations, present during the second part of the Swedish cab crashworthiness test on a Scania R-series cab, that have significance on the intrusion response.
