1. Investigation of torsion modes in overhead traveling cranes: : Reviewing the ISO 22980 standard
Master-uppsats, Linnéuniversitetet/Institutionen för maskinteknik (MT)Sammanfattning : Overhead cranes and rail mountings in the wall are subjected to vibrations whenlifting equipment. The purpose of this thesis is to review if the minimum frequencyvalue for cranes, according to the ISO 22986:2007 standard is conservative whendesigning overhead traveling cranes. LÄS MER

3. Experimental Investigation of Fluid-added Parameters on a Kaplan Runner
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : 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.

4. Development of PMSM and drivetrain models in MATLAB/Simulink for Model Based Design
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : When developing three-phase drives for Electric Vehicles (EVs), it is essential to verify the controller design. This will help in understanding how fast and accurately the torque of the motor can be controlled. LÄS MER
5. System modelling of a tightening tool
Master-uppsats, KTH/Teknisk mekanikSammanfattning : 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. LÄS MER
