    Sammanfattning : Today rubber can be found in many different applications, such as vibration dampers, tyres, clothes and gaskets. Two different types of rubbers are used today, namely the natural rubber and synthetic rubber. Natural rubber is made of a milky substance called latex, which is obtained from special trees found in tropical countries. LÄS MER

  3. 2. Wind-induced Vibration Control of Tall Timber Buildings : Improving the dynamic response of a 22-storey timber building

    Magister-uppsats, Linnéuniversitetet/Institutionen för byggteknik (BY)

    Författare :Aiham Emil Al Haddad; [2016]
    Nyckelord :timber building; wood building; structural dynamics; damping; viscoelastic dampers; 22-storey timber; wind-induced vibrations; acceleration control; increased mass; increased stiffness; ISO 10137; ISO 6897; EKS 10;

    Sammanfattning : Plans for construction of the tallest residential timber building has driven the Technical Research Institute of Sweden (SP), Linnaeus University, Växjö and more than ten interested companies to determine an appropriate design for the structure. This thesis presents a part of ongoing research regarding wind-induced vibration control to meet serviceability limit state (SLS) requirements. LÄS MER

  4. 3. Experimental Characterization of Fixtures Design: A comprehensive study on vibration minimization technique by using viscoelastic materials

    Master-uppsats, KTH/Industriell produktion

    Författare :Md Zamiul Mottasim; [2014]
    Nyckelord :;

    Sammanfattning : Damping is a phenomenon which is obviously related with dissipation of vibration energy under relative motion in a mechanical system. Without changing excitation force in many cases vibration is reduced only by changing mass or stiffness of the system just with altering the resonance frequencies. LÄS MER
