  1. 11. Numerical Assessment of Defects Effect on Boltless Composites Longitudinal Joints

    University essay from KTH/Lättkonstruktioner

    Author : Mara Santaniello; [2020]
    Keywords : ;

    Abstract : The work presented in this thesis focuses on the numerical assessment of defects effect on potential boltless design for fuselage panels longitudinal joints, typically identified as High Load Transfer (HLT) configuration. Nowadays, the state-of-art joining technique for primary aircraft composite structures, such as fuselage barrels, is still mechanical fastening. READ MORE

  2. 12. Model parameter estimation for a handheld nutrunner

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Jonathan Fridstrand; Johanna Sturk; [2020]
    Keywords : ;

    Abstract : The purpose of this project is to investigate the angled nutrunner, which is a hand held torque tool often used in the industry to tighten bolted joints. The goal is to estimate parameter values for an existing model that can describe the reaction force and the angular displacement of the tool as a function of the torque transferred to the joint.

  3. 13. Design of a Tribometer to Study Friction inThreaded Fastener Interfaces

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Zhan-Jun Lin; [2020]
    Keywords : tribometer; friction coefficient; tightening; pin-on-disc; tribometer; friktionskoefficient; åtdragning av skruvförband; pin-on-disc;

    Abstract : Bolts and nuts are one of most common joining methods since they are simple and low-cost to connect parts. Appropriate clamp force from bolted joint remains resultant joints secured, but higher/lower preload on bolted joint increases risk of the failure of mechanism. READ MORE

  4. 14. Modelling and evaluation of fasteners under fatigue

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

    Author : Vignesh Nagarajan; [2019]
    Keywords : fastener; bolted joints; failure; simulations; brott; fästelement; simulering; skruvförband; ;

    Abstract : At the calculations group in Sigma Industry East North, the traditional method for evaluating fasteners has been by use of the VDI2230 manual. As the complexity of a model increases the evaluation also becomes harder. The goal of this thesis is to set a robust evaluation method by combining the VDI2230 with the Finite Element (FE) method.

  5. 15. Influence of liquid shim on the bearing strength of a composite bolted joint

    University essay from KTH/Hållfasthetslära (Avd.)

    Author : Eric Johan Klas Voortman Landström; [2019]
    Keywords : ;

    Abstract : The objective of this thesis has been to investigate the effect a liquid shim has on the bearing strength of a composite bolted joint. The shim is necessary to close gaps that occur during the assembly of the joints, preventing the structural parts from being fastened correctly. READ MORE
