  3. 2. Analytical Investigation of Planetary Gears Instabilities and the Impact of Micro-Macro Geometry Modifications

    Master-uppsats, KTH/Farkostteknik och Solidmekanik

    Författare :Hamza Oudich; [2020]
    Nyckelord :Planetary gears; Instabilities; Resonance; Vibration; dynamic response; Spectral Iterative Method; Modal analysis; Static and dynamic transmission error; Gear mesh stiffness; Macro and micro-geometry; Phasing;

    Sammanfattning : Due to their large torque-speed ratio and transmission efficiency, planetary gears are widely used in the automotive industry. However, high amplitude vibrations remain their critical weakness, which limits their usage especially when new strict noise legislations come into action. LÄS MER

  4. 3. Dynamic simulation of a planetary gear for robots

    Magister-uppsats, Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Författare :Xiaohao Qin; Jiahao Cheng; [2019]
    Nyckelord :dynamic simualtion; robots; PGT; solidworks; MATLAB;

    Sammanfattning : Gear drives are widely applied in mechanical transmission systems and very accurate transmission systems are needed. In the robot industry, the planetary gear train (PGT) is commonly used to promote the torque transmission. One of the advantages of an ideal PGT is that the incoming torque is divided equally among the planet gear wheels. LÄS MER

  7. 5. Structural Analysis & Weight Optimization : Wheel Loader Front Axle Casings

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

    Författare :Georg Svedling; Erik Wikblom; [2017]
    Nyckelord :Wheel Loader; Weight Optimization; Topology Optimization; Strucutral Analysis; Mechanical Desing; Axle Casing;

    Sammanfattning : The purpose of this thesis work was to establish methodologies for performing structural analysis and weight optimization of wheel loader front axle casings at Volvo Construction Equipment AB (Volvo CE). A methodology for creating extensive finite element models to analyze durability with respect to both static failure and fatigue life was to be created in the software ANSYS 18. LÄS MER
