1. 16. Software Benchmark and Material Selection in an Exhaust Manifold : Thermo-mechanical fatigue simulation of an exhaust manifold in AVL Fire M

   University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

   Author : Oskar Rombo; [2018]
   Keywords : thermomechanical fatigue; TMF; simulation; viscoplastic;

   Abstract : Today, there is a great focus on downsizing the engines, this means that the engines are made smaller in size but retain the same power. This in combination with the drive to increase the power of the engines has led to the engine components being exposed to high thermal loads. Today’s engines also use very high cylinder pressure.

3. 17. Evaluation of Finite Element simulation methods for High Cycle Fatigue on engine components

   University essay from Linköpings universitet/Mekanik och hållfasthetslära

   Author : Oscar Pacheco Roman; [2018]
   Keywords : High Cycle Fatigue; HCF; Virtual Vibrations; VROM; VFEM; Virtual Channels; Random Vibrations; Engine Vibrations; FEM; Abaqus;

   Abstract : This document reflects the results of evaluating three computational methods to analyse the fatigue life of components mounted on the cylinder block; two currently in use at Scania and one that has been further developed from its previous state. Due to the cost of testing and the exponential increase in computational power throughout the years, the cheaper computational analyses have gained in popularity. READ MORE

4. 18. Minimizing Cooling Time for Diamond Anvil Cell Under High Pressure

   University essay from Lunds universitet/Mekanik

   Author : Martin Edung; [2017]
   Keywords : Diamond Anvil Cell; FEA; FEM; Structural; Transient; Temperature; Ansys; Ansys WB; Machine Drawings; ESS; European Spallation Source; Technology and Engineering;

   Abstract : The main goal of the project was to decrease the cooling time of a diamond anvil cell (DAC) by modifying an existing design. Modifications included change of materials, overall dimensions and a significant reduction of mass together with additional suggestions for decreased cool time. READ MORE

5. 19. Estimation of Fatigue Life for Welded Gears Using LEFM

   University essay from KTH/Hållfasthetslära (Avd.)

   Author : Richard Tynander; [2017]
   Keywords : ;

   Abstract : The aim of this thesis is to estimate the high cycle fatigue life of welds using finite element methods and liner elastic fracture mechanics (LEFM). Develop a new method of calculating the fatigue life that can replace the old method in use today at GKN Driveline. This is a continuation of an earlier master thesis1. READ MORE

6. 20. Thermo-mechanical Fatigue of Electrical Insulation System in Electrical machine

   University essay from Karlstads universitet/Avdelningen för maskin- och materialteknik

   Author : Ahmed Elschich; [2017]
   Keywords : Thermal mechanical fatigue; Thermo-mechanical stress; electrical machine windings; electrical insulation system; slot insulation; slot liner; groundwall insulation; conductor insulation; turn insulation; stator;

   Abstract : Electrical machines in electrified heavy-duty vehicles are subjected to dynamic temperature loadings during normal operation due to the different driving conditions. The Electrical Insulation System (EIS) in a stator winding is aged as an effect of these dynamic thermal loads. READ MORE
