  1. 6. Modeling of a ball contact with a coated plate

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

    Author : Mohammadreza Saeedi; [2023]
    Keywords : Pin on disc tribometer; coating; contact mechanics; finite element method; tribology; Pin on disc tribometer; beläggning; kontaktmekanik; finita elementmetod; tribologi;

    Abstract : During tightening of a screw, the variation in friction will affect the force acting on the joint, especially when tightening using torque as a control parameter. So, it is crucial to have a proper understanding of the contact mechanism and friction in the screw head to joint and thread interfaces. READ MORE

  3. 7. A Deep-Learning-Based Approach for Stiffness Estimation of Deformable Objects

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Nan Yang; [2022]
    Keywords : Robotic grasping; Deformable objects; Deformation modeling; Stiffness estimation; Deep learning; Robotgrepp; Deformerbara föremål; Deformationsmodellering; Styvhetsuppskattning; Djup lärning;

    Abstract : Object deformation is an essential factor for the robot to manipulate the object, as the deformation impacts the grasping of the deformable object either positively or negatively. One of the most challenging problems with deformable objects is estimating the stiffness parameters such as Young’s modulus and Poisson’s ratio. READ MORE

  4. 8. Development of extension tool for high dynamic tightening : Degree project in Mechanical Engineering, specialisation Machine Design

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Hugo Axelsson; [2022]
    Keywords : tightening; Dynamic; Extension;

    Abstract : Atlas Copco Industrial Technique AB is a global supplier of systems, software, services, and tools for the global assembly industry with keywords such as ergonomics, productivity, and traceability central to Atlas Copco’s products. The objective of the thesis was to construct a prototype tool based on the result of a previous course held at Luleå University of technology. READ MORE

  5. 9. Embedment Behavior of Steel Dowel in Timber: Influence of Moisture Content, Assembly History, and Artificial Cracks : An experimental and numerical study of embedment strength and stiffness of steel dowel in timber with different wood moisture content and assembly history

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Zijad Shehadeh; [2022]
    Keywords : Embedment strength; Embedment stiffness; Moisture content; Assembly history; Artificial cracks; Steel Dowel;

    Abstract : Timber is becoming an increasingly popular construction material particularly due to its great environmental properties. Just alone around Linnaeus University in Växjö city, dozens of multistory buildings in timber have risen. READ MORE

  6. 10. Implementation of thermomechanical laser welding simulation : Predicting displacements of fusing A AISI304 T-JOINT

    University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Author : Anton Rolseth; Anton Gustafsson; [2021]
    Keywords : Laser welding; Finite element method; ABAQUS; Thermomechanical simulation; Heat source models; DFLUX; Element activation;

    Abstract : Laser welding is an advanced joining technique with the capability to form deep, narrow, and precise welds. Numerical models are used to simulate the process in attempts of predicting distortions and stresses in the material. This is done to reduce physical testing, optimize processes and enable integrated product- and process development. READ MORE
