1. 1. Multiscale & Multiphysics Modelling of Thrust Pad (Air) Bearings

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

   Author : Nipon Roy; [2023]
   Keywords : Finite element modelling; Air bearing; Multiphysics simulations; Air lubrication; surface texture; Topology optimization;

   Abstract : Without lubrication, machines are not imaginable to perform over a long period of time and complete their designated operations. With its omnipresent availability, the air is capable of functioning as a lubricant in long operations very efficiently. Moreover, thrust bearings support axial loads and transmit power at the same time under heavy loads. READ MORE

   Keywords : Technology and Engineering;

   Abstract : Robots are nowadays present and essential in a wide range of applications, and robot arms in particular are capable of performing various tasks such as inspection, material handling, and welding. They can be classified into several types, depending on their structure and purpose. READ MORE

4. 3. Efficiency of radial piston hydraulic motors

   University essay from Umeå universitet/Institutionen för fysik

   Author : Jennifer Eriksson; [2023]
   Keywords : Efficiency; Loss mechanics; MATLAB; Simulation model; Radial piston hydraulic motor;

   Abstract : In a world with high energy cost, the efficiency of motors becomes increasingly important. Thereby, the understanding of loss mechanics is of great significance and having accurate simulation models for the efficiency of motors is crucial. READ MORE

5. 4. Improvement and verification of a pin-on-disc tribometer with variable speed and load

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

   Author : Valentine Lin; [2023]
   Keywords : tribometer; friction; tribometer; friktion;

   Abstract : The use of threaded fasteners can be found throughout the manufacturing industry due to their simplicity. When tightening a threaded fastener, the goal is to reach a desired clamping force. However, the clamping force is not directly measurable in production environments and the tightening torque is instead used to estimate the clamping force. READ MORE

6. 5. 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
