2. 1. 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

4. 2. Statistical Energy Analysis and the Individual Case

   Abstract : This doctoral thesis concerns flanking transmission in light weight, wooden multi-storey buildings within the low frequency, primarily 20-120 Hz. The overall aim is to investigate how the finite element method can contribute in the design phase to evaluate different junctions regarding flanking transmission. READ MORE

6. 4. Gearbox noise : Correlation with transmission error and influence of bearing preload

   Author : Mats Åkerblom; Sören Andersson; D. Houser; KTH; []
   Keywords : gear; gearbox; noise; vibration; transmission error; bearing preload; Mechanical engineering; Maskinteknik;

   Abstract : The five appended papers all deal with gearbox noise and vibration. The first paper presents a review of previously published literature on gearbox noise and vibration. The second paper describes a test rig that was specially designed and built for noise testing of gears. READ MORE

7. 5. Identification and Synthesis of Components for Vibration Transfer Path Analysis

   Author : Per Sjövall; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sensor placement; Indirect sensing; Vibration control; System identification; Experimental methods; Substructuring; Kalman filter; Transfer path analysis; State-space models;

   Abstract : Transmission of structure-borne vibrations in built-up structures, e.g. vehicles such as aircraft, automobiles and trains, is addressed. Methodologies for modeling, analysis, prediction and reduction of vibrations are developed. READ MORE
