  1. 6. Development of Acoustic Simulations using Parametric CAD Models in COMSOL

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Rubén Noya Pozo; Antoine Bouilloux-Lafont; [2019]
    Nyckelord :parametric CAD models; KBE; acoustic simulations; optimisation; collaboration; MDO; Parametriska CAD modeller; KBE; akustiksimulering; optimering; samarbete; MDO;

    Sammanfattning : With constantly changing regulations on emissions, heavy commercial vehicles manufacturers have to adapt for their products to preserve their quality while meeting these new requirements. Over the past decades, noise emissions have become a great concern and new stricter laws demand companies to decrease their vehicle pass-by noise target values. LÄS MER

  3. 7. Smart inventory using acoustic and radio communications

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och System

    Författare :Marika Karlsson; [2019]
    Nyckelord :Inventory; Ultrasound; Wireless communication;

    Sammanfattning : The world is getting connected in both small and bigger systems. Internet of Things (IoT) has flourished the past years and we no longer just connect our computers and phones but also our cars, wallets, keys and even the furniture and lighting in homes are talking. It is time to take things one step further, give your food and supplies a voice. LÄS MER

  4. 8. Evaluation of quantification methods for inclusion distribution in clean steel

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Felicia Fröjd; [2019]
    Nyckelord :Large area scanning; high frequency ultrasonic testing; light optical evaluation; inclusion distribution;

    Sammanfattning : Ovako products are in many cases used in high fatigue applications. Currently Ovako use ultrasonic evaluation at 10 MHz as a volumetric method for inclusion control. This study intends to investigate two new methods for quantification of micro inclusions. LÄS MER

  7. 10. Multilayered Lamination for Acoustic Board Manufacturing

    Master-uppsats, Lunds universitet/Innovation

    Författare :Angelica Madeland; [2019]
    Nyckelord :Acoustic panels; lamination techniques; sound absorption; insulation; Technology and Engineering;

    Sammanfattning : Saint-Gobain Ecophon manufactures acoustic ceiling tiles made primarily of glass wool and are interested in exploring the idea of a new manufacturing technique – using thinner layers of material and laminating these together. The possible benefits are, amongst others, the ability to use different kinds of material where they are the most useful, reduced costs, larger amounts of recycled material, less material waste, and more customizability.
