  1. 11. A measurement method for damping of drive shaft

    University essay from

    Author : Anders Bertilsson; [2019-07-03T14:13:54Z 2019-07-03T14:13:54Z 2004]
    Keywords : Samhällsbyggnadsteknik; Civil Engineering;

    Abstract : Sound in our society is beginning to be a health hazard in many places. This leads to legislation and recommendations by public authorities and governments. For a truck the sound pressure level should not exceed 80 dB(A) during a drive-by test set by international standards. READ MORE

  3. 12. Infuence of the modelling of truss joints made of hollow tube sections in finite element models

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Mattheüs Lucassen; [2019]
    Keywords : Truss joints; Circular Hollow Sections CHS ; Fatigue; Finite Element Modelling FEM ; Crane; Boom section; Local joint exibility LJF ; Stress concentration factors SCF ; Fackverksled; Cirkulära ihåliga proler; Utmattning; Finita Elementmetoden FEM ; Kran; Kranarmsektion; Lokal ledexibilitet; Spänningskoncentrationsfaktorer.;

    Abstract : Several boom segments form the crane boom. These segments are often truss structures formed out of circular hollow sections, which are welded together forming the truss joints. A adequate modelling of these truss joints is very important for operational strength and life. READ MORE

  4. 13. Optimization and development of the welding system for fiber-optic duct joints

    University essay from Mittuniversitetet/Institutionen för elektronikkonstruktion

    Author : Jiatong Duan; [2019]
    Keywords : Electrofusion welding; Fiber-optic duct; Current Measurement; dsPIC33FJ16GS404; Capacitor bank;

    Abstract : At present, the fiber optic ducts are connected by a mechanical type of joint. In this method, two ducts cut in the right angle are pushed in from both sides of the joint, and takes approximately one second to joint ducts together. READ MORE

  5. 14. Railway bridges with floating slab track systems : Numerical modelling of rail stresses - Dependence on properties of floating slab mats

    University essay from Luleå tekniska universitet/Byggkonstruktion och -produktion

    Author : Daniel Kostet; [2018]
    Keywords : ballasted track; bridge; elastic mat; expansion; finite element method FEM ; finite element analysis FEA ; floating slab mat; interaction; International union of railways UIC ; non-ballasted track; SOFiSTiK; ballasterat spår; ballastfritt spår; bro; dilatationsfogar; finita elementmetoden FEM ; finit elementanalys FEA ; fixerat spår; interaktion; Internationella järnvägsunionen UIC ; SOFiSTiK; vibrationer; vibrationsdämpande matta;

    Abstract : The increased use of continuously welded rails in the railway systems makes it necessary to increase the control of the rail stresses to avoid instability and damages of the rails. Large stresses are especially prone to appear at discontinuities in the railway systems, such as bridges, due to the interaction between the track and the bridge. READ MORE

  6. 15. Static and Fatigue Analyses of Welded Joints in Thin-Walled Tubes

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik
