1. 21. Production Process Development

   Master-uppsats, Lunds universitet/Industriell Produktion

   Författare :Richard Sundbye; Marcus Strandberg; [2019]
   Nyckelord :Technology and Engineering;

   Sammanfattning : The master thesis is a collaboration between Trelleborg AB and the division of Production and Materials Engineering at Lund University, Faculty of Engineering. The objective of the thesis has been to analyse the current production system from a lean perspective, identify an area in need of improvement and generate concrete solutions for how the studied area can be improved in terms of cost, performance and from a lean perspective.

3. 22. Quality assessment of mineral wool insulation plates : Using ultrasonic non-destructive testing

   Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Författare :Linus Ikonen; Daniel Nilsson; [2019]
   Nyckelord :Non-destructive testing; linear ultrasound; mineral wool; fibrous materials; acoustics; frequency response; signal attenuation; Oförstörande provning; linjärt ultraljud; stenull; fibrösa material; akustik; frekvenssvar; signalförsvagning;

   Sammanfattning : In the manufacturing process of mineral wool insulation plates, defects arise, such as unmelted base minerals and uncured binder which gets embedded within the plates. To be able to sort out these defective plates from a manufacturing line, a reliable quality assessment is needed. LÄS MER

4. 23. Dynamic Analysis of Sinusoidal, Random and Shock Vibration according to Launch Environment for Small Spacecraft Development to Asteroid 2016-HO3

   Master-uppsats, KTH/Lättkonstruktioner

   Författare :Akhsanto Anandito; [2019]
   Nyckelord :spacecraft; resonance frequency; sinusoidal; random vibration; shock; FEM; rymdfarkoster; resonansfrekvens; sinusformad; slumpmässig vibration; chock; FEM;

   Sammanfattning : The investment of space commerce is skyrocketing and it is predicted to be a nascent business in the future. The spacecraft demand has been growing not only for NASA and other space agency’s mission but also collaboration business between small space industries, academia, and scientific community. LÄS MER

5. 24. Non-Destructive testing of concrete with ground penetrating radar

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Byggkonstruktion och brand

   Författare :Elias Hammarström; [2018]
   Nyckelord :Concrete; Non-destructive testing; Ground Penetrating Radar GPR ; Assessment; Inspection;

   Sammanfattning : Concrete structures are susceptible to deterioration over time and it is vital to continually assess concrete structures to maintain the structural integrity and prolong the service life. In recent years there has been an increased interest in non-destructive testing of concrete, i.e. LÄS MER

7. 25. Phased Array Ultrasonic Testing of Austenitic Stainless Steel Welds of the 11 T HL-LHC Dipole Magnets

   Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

   Författare :Marcus Lorentzon; [2018]
   Nyckelord :Phased Array Ultrasonic Testing; PAUT; Non-Destructive Testing; Austenitic Stainless Steel; Welds; CERN;

   Sammanfattning : A routine non-destructive test method based on Phased Array Ultrasonic Testing (PAUT) has been developed and applied for the inspection of the first 11 T dipole prototype magnet half shell welds, and the test results are compared with the radiography and visual inspection results of the same welds. A manual scanner and alignment system have been developed and built to facilitate the inspection of the 5. LÄS MER
