  2. 1. Vibration transfer process during vibratory sheet pile driving : from source to soil

    Author : Fanny Deckner; Staffan Hintze; Kenneth Viking; Steinar Nordal; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ground vibrations; sheet piles; vibratory driving; vibration transfer process; instrumentation system; field tests; numerical modelling; vibration prediction; markvibrationer; spont; vibrodrivning; vibrationsöverföringsprocessen; instrumenteringssystem; fältförsök; numerisk modellering; vibrationsprognosticering; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : Vibratory driven sheet piles are a cost-effective retaining wall structure, and in coming decades the continued use of this method will be crucial for minimising costs within the construction sector. However, vibratory driven sheet piles are a source of ground vibrations, which may harm structures or induce disturbance. READ MORE

  4. 2. Measurements, Analysis Techniques and Experiments in Sound and Vibration : Applied to Operational MRI Scanners and in Remote Laboratories

    Author : Imran Khan; Lars Håkansson; Ingvar Claesson; Josef Ström Bartunek; Gustavo R. Alves; Blekinge Tekniska Högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active Noise Control; Remote Laboratories; Sound and Vibration Measurements; Vibration Analysis; Vibration Transmission;

    Abstract : High quality noise and vibration measurements outside of a laboratory environment on real life structures and applications are not trivial. True boundary and operating conditions enforce unique challenges on the measurements. Measurements in hazardous situations such as high magnetic fields, and high temperature environments, etc. READ MORE

  5. 3. Magneto-sensitive elastomers in vibration isolation

    Author : Ane Alberdi-Muniain; Leif Kari; N Gil-Negrete; Luigi Bregant; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Järnvägsgruppen - Effektiva tågsystem för godstrafik; Järnvägsgruppen - Effektiva tågsystem för godstrafik;

    Abstract : Vibration isolators made of rubber are used in numerous engineeringapplications to isolate structures from undesirable effects of vibrations.However, once a vibration isolator is installed in an application, it is not possible to modify its characteristics to adjust to changing conditions.

    Abstract : The present work was initiated to investigate the surface- and interfacial phenomena for iron and slag/iron systems. The aim was to understand the mechanism of the effect of surface active elements on surface and interfacial properties. READ MORE

  7. 5. Ground vibrations due to pile and sheet pile driving : influencing factors, predictions and measurements

    Author : Fanny Deckner; Staffan Hintze; Kenneth Viking; Sigurdur Erlingsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ground vibration; pile; sheet pile; prediction; markvibrationer; påle; spont; prediktion;

    Abstract : Ground vibrations due to pile driving are part of a complex process. Vibration is generated from the pile driver to the pile. As the pile interacts with the surrounding soil, vibrations are transferred at the pile-soil interface. The vibration propagates through the ground and interacts with structures, both above ground and underground. READ MORE
