  1. 1. CAE modelling of cast aluminium in automotive structures

    Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

    Författare :Subrat Singh; Sreehari Veditherakal Shreedhara; [2019]
    Nyckelord :Material failure model; LS- Dyna; Non-linear Finite Element analysis; Cast aluminium; Explicit FEA; LS-DYNA; Drop tower; Spring tower; Strut Tower; FEM; CrachFEM; ANSA;

    Sammanfattning : In the automobile industry, there is a big push for the automotive car manufacturers to base engineering decisions on the results of Computer Aided Engineering (CAE) solutions, and to transform the prototyping and testing, from a costly iterative process to a final verification and validation step. The variability in components material properties and environmental conditions together with the lack of knowledge about the underlying physics of complex systems often make it impractical to make reliable predictions based on only deterministic CAE models.

  3. 2. Development of a Mechanical Shock Test Equipment

    Master-uppsats, Lunds universitet/Innovation

    Författare :Ola Månsson; [2019]
    Nyckelord :Technology and Engineering;

    Sammanfattning : A simpler version of a shock-testing machine was developed and built. This allows engineers at Verisure to test prototypes and early versions of new products before the product is certified. An independent company shock tests the product as part of the process to certify it as an approved home alarm security product. LÄS MER

  4. 3. Validation of blast simulation models via drop-tower tests

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Joakim Rydman; [2018]
    Nyckelord :Screw; bolt; screw joint; bolted connection; simulation; model; FEM; FEA; finite element; LS-DYNA; drop-tower tests; validation;

    Sammanfattning : This study aims to validate a screw joint simulation model used by BAE Systems in LS-DYNA during blast simulations. It is important that the screw joint simulation model is physically correct, since the simulation results can influence major design decisions. LÄS MER
