1. 6. Shock absorber dynamics : A parameter study of damper physical quantitiesand their effect on automobile comfort and control

   University essay from KTH/Väg- och spårfordon samt konceptuell fordonsdesign

   Author : David Stridfeldt; Jonsson Gustav; [2023]
   Keywords : Shock absorbers; dampers; parameter study; valve dynamics; comfort; control; Stötdämpare; dämpare; parameterstudie; ventildynamik; komfort; kontroll;

   Abstract :   Damper performance is most commonly characterized by the damper’s forcevelocity behaviour. Different damper layouts and valving methods for creating oil flow constrictions bring different physical properties, outside of this conventional measure. READ MORE

3. 7. Towards a setup for narrowband terahertz generation through difference-frequency mixing of chirped ultrashort pulses

   University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Author : Isa Clementsson; [2023]
   Keywords : Physics and Astronomy;

   Abstract : Terahertz radiation is a useful tool for inducing lower-energy excitations in matter, where it can be used to cause structural changes through direct interaction with the crystal lattice. Sub-picosecond optical pulses can be used to generate intense broadband terahertz pulses through optical rectification in nonlinear crystals, reaching peak electric fields of several MV/m and conversion efficiencies as high as a few percent.

4. 8. Micromechanical Characterization of Thin Paper Materials

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen; Lunds universitet/Lunds Tekniska Högskola

   Author : Linus Bengtsson; [2023]
   Keywords : Micromechanical characterization; SEM; In situ tensile testing; Paper deformation; Fiber orientation; Paper mechanics; Technology and Engineering;

   Abstract : Hur ser framtidens hållbara förpackning ut och vad är den tillverkad av? För att besvara denna fråga blir mikromekanisk karakterisering av material en viktig parameter att utforska och förstå. I synnerhet är mikromekaniken hos tunna pappersmaterial intressant då materialet har användningspotential i flera förpackningsapplikationer. READ MORE

5. 9. Statically stable walking robot : Gait pattern generation for a quadruped using PID control

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

   Author : Awad Alnasrallah; Erik Ebbesen; [2023]
   Keywords : PID; Quadrupedal robot; Walking; Gait; Control theory; Mechatronics; Robotics; Statically stable; Self balancing; PID; Fyrbent robot; Gåendes; Gait; Reglerteknik; Mekatronik; Robotik; Statiskt stabil; Självbalanserande;

   Abstract : This report is a bachelor thesis in Mechatronics at KTH. The purpose of the thesis is to design a statically stable walking robot capable of forward movement. A quadrupedal robot is designed, as well as a PID control system. To easily control the legs with sufficient accuracy servo motors are used. READ MORE

6. 10. The design of a hydraulic equalizer bar for the feeding mechanism on forest harvester heads

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Arvid Söderlund; [2023]
   Keywords : Harvester; Harvester head; Komatsu Forest; Hydraulics; Equalizer bar; Parallellstag; Stag; Skogsmaskin; Skördare; Aggregat; Skog;

   Abstract : Due to the importance of a correct tree placement and the wear that occurs to equalizer bars inharvester heads, Komatsu Forest AB in Umeå was interested if the bar could be replaced with ahydraulic system. According to Komatsu, the problems were that the equalizer bars that are responsible forsynchronizing the delimbing knives and feeding mechanism add weight, take up space and have atendency to break before their life expectancy.
