1. 1. Additives in a steam engine to decrease friction : Friction testing of solid lubricants in powder form

   University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

   Author : Viktor Lange; [2023]
   Keywords : Tribology; friction; wear; steam; steam engine; ranotor; invencon; invencon AB; steel; contact mechanics; hexagonal boron nitride; molybdenum disulfide; tungsten disulfide; lubricants; solid lubricants; Tribologi; friktion; nötning; ånga; ångmotor; stål; kontaktmekanik; smörjning; smörjmedel; fasta smörjmedel;

   Abstract : This thesis aims to investigate the coefficient of friction between steel on steel contacts with the addition of solid lubricants such as h-BN, WS2, MoS2 in powder form, in dry conditions and wet conditions. More specifically, the purpose is to enhance the sliding between the piston rings and cylinder block in a modern high temperature steam engine developed by RANOTOR. READ MORE

3. 2. Impact of Frame Stiffness on Tribological Behaviour of Sliding Interfaces

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

   Author : Nisha Singh; [2023]
   Keywords : coefficient of friction; friction-vibration interaction; stiffness; tribometer; vibrations; friktionskoefficient; friktion-vibrationsinteraktion; styvhet; tribometer; vibrationer;

   Abstract : Friction and wear have been concerns to industrialists, scientists and environmentalist for several decades. Many robust models have been developed to address friction and wear and their dependency on various parameters. Numerous experiments have been conducted in the past to model friction and wear.

4. 3. Mechanical and tribological characterization of additive manufactured Co-alloyed tool steels aimed for cutting tool bodies

   University essay from Högskolan Dalarna/Institutionen för information och teknik

   Author : Jijesh Rajan; [2022]
   Keywords : Maraging steels; Selective laser melting; microstructure; wear; Modified 18Ni300; Osprey MAR;

   Abstract : A drill tool body operates under tough cutting conditions where it is subjected to severe rubbing at the drill flute margin by the sliding chips. The tool wear caused by the contact stresses of the high-speed sliding chips is one of the common damage mechanisms observed in drill tool bodies. READ MORE

5. 4. Evaluation of Traction Control Systems for an Electric Forklift Truck

   University essay from Linköpings universitet/Fordonssystem

   Author : Mattias Karlsson; Sebastian Johansson; [2021]
   Keywords : forklift; traction control; maximum transmissible torque; model following control; sliding mode control; slip; asr; tcs; mfc; mtte; smc; electric vehicle; master thesis;

   Abstract : This thesis evaluates different controllers for traction control on an electric forklift truck and has been done in cooperation with Toyota Material Handling Manufacturing Sweden. The need for a traction control system has increased with the introduction of lithium-ion batteries replacing the older lead-acid batteries, reducing the battery weight and therefore the downward force on the driving wheel increasing the risk for slip.

6. 5. LiDAR-Equipped Wireless Sensor Network for Speed Detection on Classification Yards

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

   Author : Isak Olsson; André Lindgren; [2021]
   Keywords : LiDAR; Internet of Things IoT ; Wireless Sensor Networks WSN ; Classification yards; 6LoWPAN; RANSAC; LiDAR; Sakernas internet; Trådlösa sensornätverk; Rangerbangårdar; 6LoWPAN; RANSAC;

   Abstract : Varje dag kopplas tusentals godsvagnar om på de olika rangerbangårdarna i Sverige. För att kunna automatiskt bromsa vagnarna tillräckligt mycket är det nödvändigt att veta deras hastigheter. En teknik som har blivit populär på sistone är Light Detection and Ranging (LiDAR) som använder ljus för att mäta avstånd till objekt. READ MORE
