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

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

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

    Sammanfattning : 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. LÄS MER

    Sammanfattning : In order to satisfy the mechanical requirements for space structures, achieving lightweight designs is of the greatest significance. The primary focus of this study is the utilization of Kelvin cell core in the design of sandwich structures for space applications. LÄS MER

  4. 3. Undersökning av relationen mellan stegljudsnivå och vibrationer : En forskningsstudie i samarbete med Derome Hus AB och Acouwood AB

    Uppsats för yrkesexamina på grundnivå, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Författare :Jakob Bülow; Jacob Johansson; [2023]
    Nyckelord :Timber structures; Impact sound; Vibrations; Träkonstruktioner; Stegljud; Vibrationer;

    Sammanfattning : Impact sound can be caused, for example, by children jumping and playing or by other types of mechanical contact with the structure. Insufficient impact sound insulation in lightweight timber structures is a recurring issue and is of great importance for the overall quality assessment of residential buildings. LÄS MER

  5. 4. Methodology for analysis of vibration isolating systems

    Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

    Författare :Jonas Olsson; [2023]
    Nyckelord :Vibration;

    Sammanfattning : Vibration causes problems in many kinds of machinery including fighter aircraft. It can, for example, cause structural fatigue, malfunction in equipment and injuries to humans. The sources of vibration are engines, flow disturbance and separation of external loads, to mention some. LÄS MER
