1. Dynamic Consequences of Bearing Radial Clearance in Jeffcott Rotors
University essay from Umeå universitet/Institutionen för matematik och matematisk statistikAbstract : Earlier research on bearing radial clearance on a vertical Jeffcott rotor is rare, but an interesting and realistic point of view in a rotor system. Applying this force to the system produces interesting results for a vertical Jeffcott rotor. READ MORE

2. Rotor Dynamic Modeling of Hydropower Rotors by 3D-Finite Element Analysis
University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikAbstract : By using the rotor dynamic capabilities of Simcenter Nastran Rotordynamics, an eigenvalue analysis of 3D-finite element models of the Jeffcott rotor and the overhung rotor were conducted and compared to the results with beam-based, lumped parameter models. The first two critical speeds of the Jeffcott rotor were estimated with variations of 3. READ MORE

3. Grid Scale Storage Placement In Power Systems
University essay from Uppsala universitet/Institutionen för elektroteknikAbstract : The increasing amount of renewable energy sources is applying more and more pressure on today’s power system. Additionally, plannable sources of energy, which are mostly non-renewable, are being decommissioned at a high rate to combat climate change. READ MORE

4. Experimental Investigation of Fluid-added Parameters on a Kaplan Runner
University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikAbstract : In order to reach climate and environmental goals, Sweden is increasing the implementation of intermittent renewable energy sources such as wind and solar power to the electricity grid. The increase of intermittent energy sources is rising power regulation requirement towards hydropower, which increasingly exposes the hydraulic turbines to high loads and fluctuating hydraulic forces.

5. System modelling of a tightening tool
University essay from KTH/Teknisk mekanikAbstract : With the help of modern computational power it has become much more common to employ simulation driven development. When performing simulations before creating prototypes and actual test, companies can reduce both the time spent on the development and the cost. READ MORE
