  1. 16. Serviceability assessment of footbridges when subjected to vibrations induced by running pedestrians

    University essay from KTH/Bro- och stålbyggnad

    Author : Javier Garmendia Purroy; [2017]
    Keywords : Footbridge; Running; Jogging; Load; Vibrations; Structural; Dynamics; Pedestrian footbridge interaction; Serviceability; Assessment; Gångbro; Löpning; Last; Vibrationer; Strukturdynamik; Bruksgränstillstånd; Bedömning;

    Abstract : Vibration serviceability in the design of footbridges is gathering enormous prominence as comfort restrictions get enhanced. Comfort verifications are often becoming critical when considering human induced dynamic loading on lightweight structures, which are increasing in slenderness and flexibility. READ MORE

  3. 17. Development of a Mechanical System to Dynamically Calibrate Pressure Sensors using a Vibrating Liquid Column

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Mugisha Macbeth Ruhweza; [2017]
    Keywords : Dynamic calibration; working liquid; pressure sensor; liquid column; Dynamisk kalibrering; arbetsvätska; trycksensor; vätskepelare;

    Abstract : This report describes a simple mechanical system developed for producing dynamic pressures of up to 50 kPa from zero-to-peak and over the frequency range 0-58 Hz. The system is constructed for dynamic calibration of pressure sensors and consists of an open tube, 30 cm in height, mounted vertically on the support plate. READ MORE

  4. 18. Investigation on Road Noise Transmission through Steering System

    University essay from KTH/MWL Marcus Wallenberg Laboratoriet

    Author : Yuan Xie; [2017]
    Keywords : Blocked force method; vehicle NVH test; coupled system;

    Abstract : An investigation on noise transmission through the steering gear system is focused on the area of vehicle NVH (Noise Vibration and Harshness). From previous investigations it is well known that noise transmission through the steering system sometimes has a significant influence referring to tire road noise. READ MORE

  5. 19. Finite Element and Dynamic Stiffness Analysis of Concrete Beam-Plate Junctions

    University essay from KTH/MWL Marcus Wallenberg Laboratoriet

    Author : Patrik Andersson; [2016]
    Keywords : Train-induced; vibrations; building; Finite Element Method; FEM; Dynamic Stiffness;

    Abstract : Measurements and predictions of railway-induced vibrations are becoming a necessity in today’s society where land scarcity causes buildings to be put close to railway traffic. The short distances mean an increased risk of the indoor vibration and noise disturbances experienced by residents. READ MORE

  6. 20. Differentiation and classification of different materials on a touch-screen using a piezoelectric contact microphone

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Anders Björn; [2016]
    Keywords : Technology and Engineering;

    Abstract : In this report, a potential improvement of an optical touch screen solution by means of acoustic sensing is presented. The goal is to utilize the different vibration patterns that arise when different materials touch the screen to be able to identify them. READ MORE
