  1. 1. Fallviktsförsök på skjuvarmerade betongbalkar

    Kandidat-uppsats, KTH/Byggteknik och design

    Författare :Louise Atterling; My Widmark; [2022]
    Nyckelord :Concrete beams; impact load; dynamic load; shear reinforcement; shock load; vibrations; signals;

    Sammanfattning : Standards and regulations for dimensioning of load-bearing structures are based on the response of load-bearing structures subjected to loads without variation in time. In the event of an accidental load, e.g. a collision or explosion, causes the load to have a rapid variation in the time resulting in a dynamic response.

  3. 2. Design and evaluation of a shock load resistant dynamic chain plate

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Daniel Olsson; [2022]
    Nyckelord :Dynamic; chain; shock load; Simulink; FEA; conveyor; wear; experimental; Nordic Quick Systems; chain plate; Simulation; FEM;

    Sammanfattning : Conveyor chains are often subject to repetitive shock loads during normal operations. This can cause accelerated wear in the chain leading to premature chain replacementor chain failure (Otoshi, 1997, p. 4). In this thesis a new approach for reducingshock load related wear in conveyor chains is proposed. LÄS MER

  4. 3. Rocket Jet Impinging on a Surface

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Javier Capel Jorquera; [2022]
    Nyckelord :Rocket jet impinging on a surface; Favre-Averaged Equations; turbulence modeling; numerical considerations; Method of Characteristics; MOC; plate optimization;

    Sammanfattning : With the continuous growth of the space industry and the introduction of reusable rockets, the number of rocket launches is expected to increase significantly in the following years. During rocket launching, the engine exhaust impinges on the launch structure producing a complex flow field. LÄS MER

  5. 4. Requirements and Analysis of an Overload Protection Mechanism for an Electromechanical Linear Actuator

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Mats Vesterberg; [2022]
    Nyckelord :EMA; Electromechanical Actuator; Linear Actuator; Shock load; Protection mechanism; Elektromekaniska ställdon; Linjära ställdon; Shocklaster; Överlastskydd;

    Sammanfattning : Cascade Drives specializes in high-performance electromechanical linear actuators (EMA). The company has developed a range of linear rack and pinion actuators based on a patented load distribution technique that allows multiple pinions to interact with a single gear rack. LÄS MER

  7. 5. Verification of elastomer characteristics in electro-mechanical linear actuator

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

    Författare :Rohit Karmungikar; [2022]
    Nyckelord :ANSYS; Aging; Hyperelastic; MATLAB and Mooney-Rivlin; ANSYS; Åldrande; Hyperelastic; MATLAB och Mooney-Rivlin;

    Sammanfattning : Cascade Drives develops electromechanical actuators using a rack and pinion configuration to achieve a combination of high load and high-speed operation. A patented load distribution mechanism enables the use of multiple pinions on a single rack, resulting in a compact unit with high positional accuracy capable of absorbing shock loads. LÄS MER
