1. Vibrations in timber floors : Dynamic properties and human perception
Sammanfattning : Springiness and vibrations of timber floors are familiar to many as a ‘live’ feelwhen walking on them, especially if living in single family housing with timberframework. Since the building regulations in Sweden changed to performancedependentrequirements in 1994 the use of timber in multifamily housing hasincreased. LÄS MER
2. Joint Interface Effects on Machining System Vibration
Sammanfattning : Vibration problems are still the major constraint in modern machining processes that seek higher material removal rate, shorter process time, longer tool life and better product quality. Depending on the process, the weaker structure element can be the tool/tool holder, workpiece/fixture or both. LÄS MER
3. Floor vibration : dynamic properties and subjective perception
Sammanfattning : This thesis covers research in the floor vibration field. Although lightweight steel framed constructions have been in focus, many results are applicable to floors in common and to some extent also to vibrations in general. LÄS MER
4. Vibration mitigation of high-speed railway bridges : Application of damping devices in theory and practice
Sammanfattning : The dynamic response of railway bridges is an important aspect to consider, as the repetitive loading from passing trains may result in excessive vibrations of the bridge deck. Several design criteria are developed in order to assure the structural safety and passenger comfort during train crossings of a bridge. LÄS MER
5. Towards semi-automation of forestry cranes : automated trajectory planning and active vibration damping
Sammanfattning : Forests represent one of the biggest terrestrial ecosystems of Earth, that can produce important raw renewable materials such as wood with the help of sun, air and water. To efficiently extract these raw materials, the tree harvesting process is highly mechanized in developed countries, meaning that advanced forestry machines are continuously used to fell, to process and to transport the logs and biomass obtained from the forests.
