1. 1. Validation of a moderate Reynolds number channel in Neko

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Shicheng Dai; [2023]
   Keywords : Neko; CFD; DNS; Turbulence channel flow;

   Abstract : Neko is a portable framework for high-order spectral element flow simulations[1]. Originally from Nek5000, Neko not only inherited its numerical stability and well-performance, but also added the benefits of dynamic memory and support for many current accelerator backends. READ MORE

3. 2. Evaluation of Coefficient of Friction in Oblique Helmet Impacts: An Experimental and Numerical Study

   University essay from KTH/Hållfasthetslära

   Author : Philip Singh; [2022]
   Keywords : FE model; friction; helmet impact; LS-DYNA; FE-modell; friktion; hjälmislag; LS-DYNA;

   Abstract : The focus of this thesis was to increase the knowledge in the area of "dynamic friction" during oblique helmet impacts, both experimentally and numerically. Physical experiments have been performed with multiple helmets, different angles of the anvil and different surface materials, with results of impact forces from the anvil and accelerations of the head.

4. 3. Effects of Dynamic Modeling on the Path Planning of Simulated Autonomous Vehicles

   University essay from Linköpings universitet/Fordonssystem; Linköpings universitet/Tekniska fakulteten

   Author : Elin Kidell Löwstedt; [2022]
   Keywords : ;

   Abstract : The purpose of the thesis was to evaluate the robustness of the Hybrid A* algorithm in regards to the levels of dynamic vehicle modeling, vehicle parameters and driving velocity. The original scope of the thesis project was to alter vehicle and tire models but this was discovered to be out of the time limits of the thesis project. READ MORE

5. 4. Development of a 3D Ring Dynamics Model For a Heavy-Duty Piston Ring-Pack

   University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Author : Parthasri Akurati; Karan Kumar; [2021]
   Keywords : 3D ring model; Flank wear; Oil consumption; Piston ring dynamics;

   Abstract : With the increasing restrictions in emission legislations, the automotive industry aims to improve the efficiency of the lubricating system and to decrease fuel consumption. In the power cylinder unit (PCU), the piston rings are the major contributor to these consumptions. READ MORE

6. 5. Comparative study of the static and quasi-static compliance measurement procedures on industrial manipulators

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Katrin Kersch; Anwar Ahmad Rana; [2021]
   Keywords : industrial manipulators; stiffness; compliance calibration; pose accuracy; Industriella manipulatorer; stelhet; efterlevnadskalibrering; positionsnoggranhet;

   Abstract : Serial articulated industrial manipulators are increasingly used in machining applications due to their flexibility in application and their cost-effectiveness compared to conventional machinery. However, the use of industrial manipulators in machining processes that subject the robot to high loads such as in drilling is limited. READ MORE
