  1. 16. Shock Load Absorption of Electro-mechanical Actuators

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Kenan Güler; Milan Andelkovic; [2021]
    Keywords : Shock loads; electro-mechanical actuators; load absorption; Stötbelastningar; elektro-mekaniska ställdon; dämpningsförmåga;

    Abstract : När ett ställdon får som krav att kunna överföra höga krafter i relativt höga hastigheter med en dessutom väldigt hög precision är elektromekaniska ställdon oftast att föredra. En traditionell pinjong-kuggstång-uppställning uppfyller vissa av de kraven, men om kraften ska ökas behövs det fler än ett pinjongpar. READ MORE

  3. 17. Compliance of a Robot Arm using Torque-Based Cartesian Impedance Control

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Oussama Chouman; [2021]
    Keywords : Technology and Engineering;

    Abstract : Robots have become important for the development of today’s society. They are known to obtain good accuracy and repeatability of tasks that either complement or replace human labour. READ MORE

  4. 18. Dynamic Torque Modeling of a Wet Lamella Clutch Pack

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Jacob Wallersköld; Johan Appelros; [2021]
    Keywords : wet lamella clutch; friction modeling; torque modeling; torque accuracy; force measurements; system identification; grey-box modeling; Technology and Engineering;

    Abstract : Wet lamella clutches are used in the automotive industry to enable all-wheel drive and thereby increase acceleration, handling and safety of cars. The clutches work by transmitting torque from an incoming- to an outgoing shaft through a series of lamella - steel-disc friction surfaces (lamella pack), lubricated by an oil. READ MORE

  5. 19. Comparison of high density and bipolar surface EMG for ankle joint kinetics using machine learning

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Federica Aresu; [2021]
    Keywords : EMG; HD-sEMG; machine learning; joint torque;

    Abstract : The relationship between sEMG signals and muscle force, and associated joint torque, is an object of study for clinical applications such as rehabilitation robotics and commercial applications as wearable motion control devices. The information type and quality obtained by sEMG can impact the classification and prediction accuracy of ankle joint torque. READ MORE

  6. 20. Extended and Unscented Kalman Filtering for Estimating Friction and Clamping Force in Threaded Fasteners

    University essay from Uppsala universitet/Signaler och system

    Author : Mohammad Al-Barghouthi; [2021]
    Keywords : Estimation Theory; Extended Kalman Filter; EKF; Unscented Kalman Filter; UKF; Observability; Friction; Clamping Force; Tightening; Torque Controlled; Bolt; Threaded Fasteners;

    Abstract : Threaded fasteners tend to break and loosen when exposed to cyclic loads or potent temperature variations. Additionally, if the joint is held tightly to the structure, distortion will occur under thermal expansion issues. READ MORE
