1. 21. Development Model of a Gas Pressure Regulator for Spacecraft Propulsion : Design Enhancement and Testing

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

   Author : FILIPPO POZZI; MARCUS SJÖBERG; [2021]
   Keywords : ;

   Abstract : This thesis treats the testing, analysis, and continued development of a mechanical pressure regulator prototype, intended for use in spacecraft propulsion systems. Herein referred to as the Adapted Mechanical Pressure Regulator (APR), the regulator is an adaptation made by the Swedish space system developer OHB Sweden AB (OSE) of an existing patented design originally intended for use outside of the space industry.

3. 22. Simulation of Mechanical Shock with Finite Element Analysis and Estimation of Shock Attenuation

   University essay from KTH/Hållfasthetslära

   Author : Cheng Qian; [2021]
   Keywords : shock; SRS; FEA; attenuation; chock; SRS; FEA; chockdämpning;

   Abstract : Space equipment is often subjected to mechanical shocks. Some devices like electronics are sensitive to shocks, and they can easily be damaged. To protect these devices, it is important to study shock penetrations in space structures. The Finite Element Method is an effective tool to simulate response to transient excitations. READ MORE

4. 23. Modelling of air-gap harmonic torques and its impact on vibrations in electric drivetrains : Modelling interaction between electromagnetics and vibration of an electrical machine

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Dhiyanesh Radhakrishnan; [2021]
   Keywords : Electro-Magnetics; Eigenfrequency; Electrical Machine; Multi-Body Dynamics; Displacement; machine vibrations; Elektromagnetik; Eigen frekvens; Elektrisk maskin; Flerkropps dynamik; Förskjutning; maskin vibrationer;

   Abstract : In this report, the effect of external torque injection of a particular phase and frequency was analyzed using an induction motor assembly consisting of a prototype of an induction motor and a flexible mounting arrangement. The eigenfrequencies of the several components that make up the construction of the induction machine assembly are found out both by analytical and FEM methods. READ MORE

   Abstract : Kongsberg Automotive is developing a brand-new actuator for engaging and disengaging a clutch for different driveline applications. This master thesis research improves the concept design of the shift fork for the new Dog-Clutch Actuator using Design for Manufacturability (DFM). READ MORE

6. 25. HVDC transformer core resonance calculation

   University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Author : Axel Thorstrand; [2021]
   Keywords : HVDC; High Voltage Direct Current; Transformer core; Natural frequencies; Energy method-based equation; HVDC; Högspänning likström; Transformatorkärna; Naturliga frekvenser; Energimetod;

   Abstract : Transformers emit a characteristic humming noise due to magnetostriction which is the continuous change in dimensions during magnetization. The noise is amplified if the induced frequencies match the core’s natural frequencies, consequently avoiding geometries that create resonance is critical in order to fulfill customer sound level requirements.
