  1. 1. A bonded discrete element approach to simulate loading with hydraulic mining excavators

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

    Author : Carl Andersson; [2021]
    Keywords : DEM; bonded DE; granular material; hydraulic excavator; wear; Archard s wear law; LS-DYNA; simulation;

    Abstract : When operating hydraulic mining excavators the loading equipment is exposed to harsh conditions which lead to extensive wear of the equipment, especially the bucket and bucket teeth. Simulations are used to better understand the wear development and to evaluate new methods to operate excavators more efficiently. READ MORE

    Abstract : This thesis work is carried out in collaboration with Olofsfors AB. They manufacture steel products such as tracks and chains for forest machines and wear steel for plows and graders. The focus of this project is on wear steel. READ MORE

  4. 3. A study of wear and load behaviour on bucket teeth for heavy-duty cable shovels

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

    Author : Jamal Choudhry; [2020]
    Keywords : DEM; FEM; bucket; teeth; cable shovel; wear; Archard s law; LS-DYNA; scan;

    Abstract : Many of today’s engineering advancements rely on minerals such as copper, gold and iron. For this reason, the mining industry plays an important role for the development of society and technological wonders. Mining excavators are commonly used tools for extracting the minerals from the mine. READ MORE

  5. 4. PREVENTION OF WHEEL WEAR, A CASE STUDY : Developing a functioning wheel profile for rail-mounted transportation trolley.

    University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Keywords : Wear prediction; Rail; Flanged wheel; Archards model; Hertzian contact problem; Abrasive wear; Adhesive wear; Theorethical prediction model;

    Abstract : This bachelor’s degree project aimed to improve the wheel profile of a rail mounted trolley and determine the cause of wheel failure. The proceedings of this project where modelled after an approach for solving wear problems with an emphasis on designing for sustainability. READ MORE

  6. 5. Analysis oft yre wear using the expanded brush tyre model

    University essay from KTH/Fordonsdynamik

    Author : Mahdi Mohammadi; Ray Ngeno; [2015]
    Keywords : ;

    Abstract : Approximately 60 000 tonnes of tyres are produced annually in Sweden to meet thedemand in the market. It is believed that 10 000 tonnes of rubber particles contaminatesthe Swedish roads every year. Some of the elements in the emitted particles cannegatively impact the environment. READ MORE
