This degree project examines the feasibility of implementing a community of practice within the contract education course ”Sustainable Transport Systems” offered at KTH Royal Institute of Sweden in collaboration with Scania. This degree project aims to investigate if it would be possible to increase participation in the course by creating study cir...
With the increased focus on reducing carbon emissions in today’s society, several industries have to overcome new challenges, where especially the automotive industry is under a lot of scrutiny to deliver improved and more environmentally friendly products. To meet the demands from customers and optimize vehicles aerodynamically, new cars often con...
Vibration measurement systems containing sensors, signal conditioning, and data acquisition devices, are important for monitoring motors, gearboxes, turbines, etc. Microelectromechanical and piezoelectric sensors are predominantly used for vibration measurements. However, they are not cost-effective, flexible in design, and incapable of self-poweri...
The current work focuses on predicting the buckling and free vibration frequencies (fn) of cenosphere reinforced epoxy based syntactic foam beam under varying loads. Critical buckling loads (Ncr) and fn are predicted using the differential quadrature method (DQM). Ncr and fn have been calculated for beams of varying cenosphere volume fractions subj...
This thesis discusses how large manufacturing incumbent companies potentially can ensure their longevity and future-proof themselves by infusing ambidexterity throughout their organizations. Ambidextrous companies are equipped to achieve success in both current and future business environments, providing valued solutions to customers today and in t...
Indexator Rotator Systems AB i Vindeln utvecklar och tillverkar hydrauliska rotatorer för vridpositionering av verktyg såsom gripare relativt en kranarm, framför allt på skogsmaskiner. En orsak till slitage i rotatorer kan vara att metallfragment följer med hydraulvätskan i hydrauliksystemet och verkar som slippapper med slitage som följd. En väsen...
High accuracy autonomous positioning systems are becoming increasingly important in today’s chemical industry because they can obtain precise experiment results automatically and hence allow lab technicians to focus on other tasks concurrently. One time consuming process is the process of sampling chemical test results into the correct container, e...
The implementation of automated systems in manufacturing industries increases efficiency, precision, and safety by reducing human intervention, errors, and waste. Variable loads can cause several problems for automation systems. One of the most significant challenges is maintaining the stability and precision of the production process despite chang...
The flight control actuation system is one of the most critical systems in an aircraft. A failure of this system cannot occur, since it would have catastrophic consequences. The environment it operates in is considered as highly demanding, with temperatures ranging from -50 to +60 degrees Celsius, speeds from 0 to Mach 2+ and G-forces from -3 up to...
Hyperelasticity is a significant property of rubber, taken advantage of in engineering applications. A common application is the use of seals to prevent fluid transfer (liquid or gas) between solid regions. Volvo CE is often depending on external supplier when developing seals. However, it could be beneficial to be able to do design and analysis in...
