1. 21. Analysis of Footbridge Comfort Vibrations

   University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

   Author : Niklas Thuresson; Henrik Ruuth; [2023]
   Keywords : footbridges; dynamics; vibrations; accelerations; Sétra; comfort vibrations; natural frequencies; Technology and Engineering;

   Abstract : The aim of this master's thesis was to investigate and increase the knowledge of how different parameters affect the dynamic properties of steel beam bridges used for pedestrian traffic. Steel footbridges are commonly used due to their high strength and low weight. READ MORE

3. 22. Comfort of children in cycle carriers

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

   Author : Yunqi Liu; [2022]
   Keywords : Bicycle carrier; Child comfort; Laboratory experiment; ISO 2631-1; Cykelsläp; Barns komfort; Laboratorieförsök; ISO 2631-1;

   Abstract : Carriers attached as bicycle trailers that can transport small children are becoming increasingly popular in recent years. They replace cars as a convenient and sustainable way to travel for families in commuting and other everyday activities. READ MORE

4. 23. Utilisation of hardwood in cross-laminated timber - A numerical study on vibrations in floors

   University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

   Author : Johannes Jonasson; Olle Karlsson; [2022]
   Keywords : hardwood; birch; beech; clt; cross-laminated timber; vibrations; floors; footfall; accelerations; Technology and Engineering;

   Abstract : Cross-laminated timber (CLT) is an engineered wood product consisting of several layers of laminations bonded together with adhesives. In contrast to heavier construction materials, timber and other lightweight building materials are more prone to serviceability issues due to vibrations. READ MORE

5. 24. Vibration-Based Terrain Classification for an Autonomous Truck

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

   Author : Lucas Lovén; [2022]
   Keywords : Autonomous vehicles; machine learning; surface identification; obstacle identification; signal processing; time series classification; Autonoma fordon; maskininlärning; detektering av underlag; detektering av hinder; signalhantering; tidsserie klassifiering;

   Abstract : This thesis is focused on developing vibration based terrain classification for an autonomous mining truck. The goal is to classify between good and bad gravel roads as well as good and bad asphalt roads. Current literature within vibration based terrain classification has been focused to a great extent on smaller research vehicles. READ MORE

6. 25. Reliability-Based Sensitivity Analysis of the Dynamic Response of Railway Bridges

   University essay from KTH/Bro- och stålbyggnad

   Author : Hasan Al-Zubaidi; [2022]
   Keywords : Railway bridges; High-speed trains; Simply supported beam; Global sensitivity analysis; Uncertainty quantification; Reliability; Ballast instability; Running safety; Passenger comfort;

   Abstract : In response to the planned increase in operational speeds and axle loads of passengertrains that may lead to resonance-induced excessive vibrations in railway bridges,recent studies examined the reliability of bridges concerning train running safety andpassenger comfort limit states. In this respect, valuable information regarding theimportance of input variables can be obtained by conducting Sensitivity Analysis (SA). READ MORE
