  1. 11. Design of Eccentric Double Amplitude Vibration Drum Roller Shaft with Improved Mass Moment of Inertia : Product Development of Compaction Equipment

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Marika Blad; Alexander Tynnerstål Balog; [2020]
    Keywords : Eccentricity; mass moment of inertia; double amplitude feature; vibration; Excentricitet; masströghetsmoment; dubbelamplitud; vibration;

    Abstract : Road construction is important to make transports safe and sustainable. To compact asphalt an amount of energy needs to be conducted into the material either by static pressure or dynamic vibrations. An asphalt-roller compact the material and increases its load-bearing capacity. READ MORE

  2. 12. Stability analysis and modelling of a structure with corrugated roof

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Nikola Tosovic; [2020]
    Keywords : Technology and Engineering;

    Abstract : Corrugated galvanized iron (CGI), or corrugated sheet metal, is a lightweight roofing material that was invented in the early 1800s. The corrugation gives the steel an increased flexural strength in its installed direction and thus increases the amount of load the CGI-plate is able to carry and the span it can be effective at.

  3. 13. EXPERIMENTAL CHARACTERIZATION AND COMPUTATIONAL DYNAMIC MODELLING OF A VIOLIN Analysing the effects of creep and string tension

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Joel Värelä; Erik Tunlid; [2020]
    Keywords : Violin; experimental modal analysis; modal analysis; EMA; finite element method; FEM; FE; wood; Technology and Engineering;

    Abstract : During the 17th and early 18th century Antonio Stradivari built around 900 violins, that still today are considered some of the best instruments ever created. The theories of how it was possible for a luthier active 300 years ago to create instruments of this quality are many, including unique wood properties and secret building techniques. READ MORE

  4. 14. Virtual testing of self-piercing rivet connections

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Daniel Andersson; Fredrik Saliba; [2020]
    Keywords : FEM; SPR; self-piercing rivets; self piercing rivets; LS-dyna; Explicit FEM; lap-shear; cross-tension; KS2; r-adaptivity; 2D axisymmetric; axisymmetric;

    Abstract : The automotive industry is currently trying to replace the conventional steels to lightweight materials such as aluminum or carbon fiber to meet all stricter emission targets. When using such materials, traditional joining methods, such as spot welds, could be difficult to use. Therefore, more focus has been put on self-piercing rivets (SPR). READ MORE

  5. 15. CAE modelling of cast aluminium in automotive structures

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : Subrat Singh; Sreehari Veditherakal Shreedhara; [2019]
    Keywords : 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;

    Abstract : 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.
