1. 16. Reduction of vibration transmitted through car seats : A study to reduce test drivers’ whole-body vibrations at Volvo Car Group’s test facility

   University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Author : Malin Fellenius; [2017]
   Keywords : Ergonomics; Front seat; Whole-body vibration;

   Abstract : Present thesis will concentrate on the attention to reduce the input of whole-body vibrations transmitted to test drivers in durability tests. On behalf of Volvo Cars, the purpose has been to develop a concept solution on the driver's seat. Solving this problem is significant due to test driver’s safety and theirs ergonomically conditions.

3. 17. Dynamic Soil-structure Interaction of Portal Frame Bridge Walls for High-speed Railways

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

   Author : Henrik Malm; [2016]
   Keywords : SSI; Soil-structure interaction; Structural dynamics; High-speed railway bridges; Impedance; Receptance; Finite element method; Portal frame bridge; Technology and Engineering;

   Abstract : In Sweden, high-speed railways is a subject for public debate. The first stage of a high-speed train network, Ostlänken between Stockholm and Linköping, is under investigation, and is planned to be trafficked in 2028. The high-speed railway is intended to hold traffic with speeds up to 320 km/h. READ MORE

4. 18. Predicting Railway-Induced Ground Vibrations

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

   Author : Nils Persson; [2016]
   Keywords : ground vibrations; railway; train; wave propagation; vibration measurements; finite element method; dynamics; Technology and Engineering;

   Abstract : Population growth and densification lead to growing urban environments. Unbuilt land within cities can be used to construct residences and other facilities. Population growth can further lead to a greater demand of transportation, which can require expansion of transportation systems such as railways or road traffic. READ MORE

5. 19. Borehole Dimension Impact on LHD Operation in Malmberget Mine

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Markus Danielsson; [2016]
   Keywords : LHD; sublevel caving; fragmentation;

   Abstract : Sublevel caving is a highly mechanizable mass mining method normally utilized in large, steeply dipping orebodies. The fragmented ore flows freely, aided by gravity, down to the drawpoint while the surrounding waste rock caves in due to induced stresses and gravity. READ MORE

6. 20. Numerical analysis of vibrations due to impact pile driving

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

   Author : Sebastian Andersson Olivecrona; Rasmus Sulander; [2016]
   Keywords : Finite element method; Concrete pile; Impact pile driving; Ground vibrations; Soil mechanics; Soil dynamics; COMSOL Multiphysics; Technology and Engineering;

   Abstract : Vibrations originating from constructional work can affect the nearby soil and structures. Depending on the properties of the vibrations, these can result in settlements in the soil and damages to existing structures. Along with blasting, impact pile driving is one of the greatest sources of vibrations on a construction site. READ MORE
