  1. 1. Three-Dimensional Load-Deformation Relationships of Arbitrarily Loaded Coiled Springs

    Författare :Lars Lindkvist; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; extended stiffness model; helical spring; non-linear deformation; stiffness matrix; coiled spring; arbitrary load; large deformation; three-dimensional;

    Sammanfattning : This paper reports the development of a computer based tool that can be used to predict the three-dimensional load-deformation relationships of arbitrarily loaded coiled springs. The non-linear deformation of the spring is calculated by dividing the spring into small elements for which the load-deformation relationships can be considered to be linear. LÄS MER

  3. 2. Some Aspects of Wear and Structural Dynamics

    Författare :Jakob Knudsen; Hållfasthetslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration and acoustic engineering; Mechanical engineering; hydraulics; chaos; interfacial breakdown; stability; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik; vacuum technology; fretting wear; fretting map; vibro-impact dynamics;

    Sammanfattning : The topic of this thesis is dynamics and wear of structures. In the six appended papers different aspects of wear and dynamics of a model system are studied. The considered system consists of a long slender rod with unilateral supports, subject to harmonic and stochastic excitation. LÄS MER

  5. 4. Contact stiffness in tyre/road noise modelling and speed dependencies of tyre/road noise generation mechanisms

    Författare :Julia Winroth; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tyre road noise; Air-pumping; Tyre road contact stiffness; Speed exponent analysis; Tyre road contact modelling;

    Sammanfattning : Tools for simulating tyre/road noise are highly valuable in the efforts to limit the negative consequences of road traffic noise.A numerical tyre/road noise simulation tool was in this study used to investigate how the contact stiffness parameter affects the predicted tyre/road noise.

  7. 5. Have you heard about wire? Monitoring of the wire drawing process

    Författare :Joakim Larsson; Christer Korin; Anton Jansson; Patrik Karlsson; Rachel Pettersson; Diana Janis; Örebro universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wire drawing; process monitoring; condition monitoring; drawing force; performance monitoring;

    Sammanfattning : Wire made from metal is a fundamental component found in almost every complex product, ranging from a simple pen to a spacecraft. It is used to manufacture nails, screws, springs, rivets, cables, welding electrodes, and numerous other items that surround us daily. LÄS MER
