1. 6. Requirements and Analysis of an Overload Protection Mechanism for an Electromechanical Linear Actuator

   Master-uppsats, KTH/Maskinkonstruktion (Inst.)

   Författare :Mats Vesterberg; [2022]
   Nyckelord :EMA; Electromechanical Actuator; Linear Actuator; Shock load; Protection mechanism; Elektromekaniska ställdon; Linjära ställdon; Shocklaster; Överlastskydd;

   Sammanfattning : Cascade Drives specializes in high-performance electromechanical linear actuators (EMA). The company has developed a range of linear rack and pinion actuators based on a patented load distribution technique that allows multiple pinions to interact with a single gear rack. LÄS MER

3. 7. Finite Element Analysis of Stresses in the MIST CubeSat due to Dynamic Loads During Launch

   Master-uppsats, KTH/Lättkonstruktioner

   Författare :Carl Järmyr Eriksson; [2021]
   Nyckelord :Satellite; CubeSat; Nanosatellite; Dynamic Loads; Launch Loads; Finite Element Analysis; FEA; Quasi-static Acceleration; Modal Analysis; Random Vibration; Shock Loads; satellit; CubeSat; nanosatellit; dynamiska laster; uppskjutningslaster; finita elementmetoden; FEM; kvasistatisk acceleration; modalanalys; stokastiska vibrationer; chocklaster;

   Sammanfattning : A finite element model of the CubeSat MIST was created, in order to assess the stresses that occur in the satellite in response to loads during its launch. Due to size limits of thesoftware used, simplifications had to be made to the geometry of the model. LÄS MER

4. 8. Performance of reinforced concrete bridges strengthened with Carbon Fiber Reinforced Polymers : Case study: Essinge Bridge over Pampaslänken

   Master-uppsats, KTH/Bro- och stålbyggnad; KTH/Jord- och bergmekanik

   Författare :Zeinab Mirzahassanagha; Eva Malo; [2021]
   Nyckelord :CFRP; External Strengthening Method; RC Bridges; Curved Substrate; Finite Element Modelling; Kolfiberväv; Extern Förstärkningsmetod; Betongarmerade broar; Konkav yta; Finita Elementa Modellering;

   Sammanfattning : This master thesis deals with the performance of existing reinforced concrete bridges strengthened with externally bonded carbon fibre reinforced polymers (CFRP). One of the main aims of this work is to understand the functionality of such an external strengthening method applied to a concave surface in a heavy concrete structure such as a bridge. LÄS MER

5. 9. Dynamic Blast Load Analysis using RFEM : Software evaluation

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Författare :Oskar Dädeby; [2021]
   Nyckelord :Blast load; Dynamic; RFEM; time history; experiment; time step;

   Sammanfattning : The purpose of this Master thesis is to evaluate the RFEM software and determine if it could be used for dynamic analyses using blast loads from explosions. Determining the blast resistance for a structure is a growing market and would therefore be beneficial for Sweco Eskilstuna if RFEM could be used for this type of work. LÄS MER

7. 10. Numerical simulations of shear reinforced concrete beams subjected to blast loads

   Master-uppsats, KTH/Betongbyggnad

   Författare :Anton Frank; Andreas Fristedt; [2021]
   Nyckelord :Numerical simulations; shear reinforcement; blast loads; dynamic shear failure; Numeriska simuleringar; tvärkraftsarmering; luftstötvåg; dynamiskt skjuvbrott;

   Sammanfattning : Historical accidents and experimental investigations have made apparent that blast loaded concrete members are prone to fail in brittle shear rather than a ductile flexure mode. Air blasts from accidental detonations or explosives may cause severe damage to buildings and infrastructure and it is of great importance that load carrying members can withstand the impulse that arise to avoid progressive collapses.
