  1. 1. Dynamic response of damped attachments in fighter applications

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Katja Nordström; [2023]
    Keywords : Vibration isolator; printed circuit board; vibrations; natural frequency; Vibrationsisolator; kretskort; vibrationer; resonansfrekvenser;

    Abstract : This thesis investigates the impact of vibration isolators on circuit boards during harsh vibrationenvironments that occur when they are mounted on the wings of a fighter jet. To examine thisphenomenon, a mathematical model and a simulated model were developed to determine theresonant frequencies of the circuit board under various boundary conditions. READ MORE

  2. 2. Numerical modeling and experimental investigation of large deformation under static and dynamic loading

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Benjamin Bondsman; [2021]
    Keywords : Total Lagrangian; Updated Lagrangian; Newmark; Energy Conserving; Algorithm; Numerical; Modeling; Large; Deformation; steel; Wood; Pine; Plane Strain; 3D;

    Abstract : Small kinematics assumption in classical engineering has been in the center of consideration in structural analysis for decennaries. In the recent years the interest for sustainable and optimized structures, lightweight structures and new materials has grown rapidly as a consequence of desire to archive economical sustainability.

  3. 3. Dynamic Analysis of Portal Frame Railway Bridges - Case Studies Investigating the Structural Response

    University essay from Lunds universitet/Avdelningen för Konstruktionsteknik; Lunds universitet/Institutionen för bygg- och miljöteknologi

    Author : Benjamin Berg; Pontus Nyberg; [2020]
    Keywords : Dynamic Analysis; Portal Frame Bridges; High Speed Trains; Railway Bridges; Finite Element; Resonance; Modal Analysis; BRIGADE Plus; Technology and Engineering;

    Abstract : As the world continues to see an increase in carbon dioxide emissions, actions aiming towards reducing man's negative impact on the environment are paramount. To be able to compete with the air travel industry, the Swedish Transport Administration suggests a vast expansion of the existing railway system. READ MORE

  4. 4. Dynamic Design of Bridges on High-Speed Railway Lines

    University essay from Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Byggnadsmekanik

    Author : Felicia Nilsson; Filippa Dahl; [2019]
    Keywords : High-speed railway bridges; bridge-train resonance; structural dynamics; modal dynamics; time stepping; soil-structure interaction; finite element method; BRIGADE Plus; Technology and Engineering;

    Abstract : In recent years, high-speed railway has been on the upswing in the public debate, as Swedish authorities have affirmed the plans of a high-speed corridor connecting Stockholm, Gothenburg and Malm¨o. The track speed limit is not fully determined, but will be in the range of 250-320 km/h. READ MORE

  5. 5. Dynamic analysis of high-rise timber buildings : A factorial experiment

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Victor Karlberg; [2017]
    Keywords : Acceleration; comfort criteria; cross-laminated timber; factorial design; finite element analysis; natural frequency; vibrations; Acceleration; komfortkrav; korslimmat trä; faktorförsök; finita elementmetoden; naturlig egenfrekvens; vibrationer;

    Abstract : Today high-rise timber buildings are more popular than ever and designers all over the world have discovered the beneficial material properties of timber. In the middle of the 1990’s cross-laminated timber (CLT), was developed in Austria. CLT consists of laminated timber panels that are glued together to form a strong and flexible timber element.
