  1. 11. Engine and Gearbox Thermal Management Modeling

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Amaury Arlotto; [2018]
    Keywords : ;

    Abstract : In order to improve the global efficiency of an engine within the French company Groupe PSA, a research axis focuses on gearbox thermalmanagement for a quicker reduction of its own friction losse after a cold start. The principle remains in deriving a little part of the coolant energy towards the gearbox – until now heated by its own internal frictions – as long as the impact on the engine warm-up is low enough for a global final gain.

  3. 12. Large Eddy Simulation of Turbulent Flow over a Backward-Facing Step

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Edmond Shehadi; [2018]
    Keywords : ;

    Abstract : This work studies the effect of grid resolution and subgrid scale modeling on the predictive accuracy of Large Eddy Simulation. In particular, the problems considered are: turbulent flow over a backward-facing step and fully-developed turbulent channel flow. READ MORE

  4. 13. 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.

  5. 14. Nonlinear Finite Element Analysis of Shrinking Reinforced Concrete Slabs-on-ground

    University essay from KTH/Betongbyggnad

    Author : Shruthi Prakash; [2018]
    Keywords : Slabs-on-ground; Gradient shrinkage; Statical indeterminate structure; Vertical deflection and Cracking;

    Abstract : Concrete slabs-on-ground are commonly used in many types of industrial floors, warehouses, highways, parking lots and buildings. Cracks and deflection of slabs are undesired events caused by differential shrinkage, which limits the service life of the slabs. READ MORE

  6. 15. Investigation of factors affecting cracking during forming of truck cab body parts

    University essay from Umeå universitet/Institutionen för fysik

    Author : Evelina Salomonsson; [2018]
    Keywords : ;

    Abstract : Sheet metal forming is a technique widely used in todays industries as it enables fast transformation of metal sheets into parts of various shapes and sizes. Volvo GTO EBM in Umeå uses sheet metal forming in their production of truck cab body parts, and a challenge common for all industries using this technique is to avoid cracking in the formed metal.
