  2. 1. Demystifying the effectiveness in design of production systems - Investigating the coupling between acquisition and maintenance of equipment

    Author : Malin Hane Hagström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; early equipment management; maintenance management; engineering knowledge management; manufacturing engineering; equipment acquisition; production system design;

    Abstract : The purpose of the design of production systems is to create systems that perform according to set targets. With the paradigm shift towards electrification and digitalisation, manufacturing engineers in the heavy truck powertrain industry face several unexplored challenges; in the products for which they are designing production, in the equipment they are purchasing to realise production systems, and finally, in the digitalisation impact on engineering processes.

  4. 2. Effects of top-of-rail friction modifiers on the friction, wear and cracks of railway rails

    Author : Saad Ahmed Khan; Jan Lundberg; Rolf Dollevoet; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Abstract : The railway is an economical and environmentally friendly mode of transport for long distances and heavy loads. The demands on the operators are increasing with increased competition in the market, and therefore they are currently demanding more track capacity. In the short term, the existing network is expected to deliver the increased capacity. READ MORE

  5. 3. Development of a Novel Method for Lithium-Ion Battery Testing on Heavy-Duty Vehicles

    Author : Pontus Svens; Mårten Behm; Göran Lindbergh; Per Alvfors; Anders Malmqvist; KTH; []
    Keywords : Lithium-ion battery; HEV; field testing; heavy-duty vehicles;

    Abstract : Increasing demands for lower environmental impact from vehicles, including heavy-duty vehicles, have driven several vehicle manufacturers to consider adding hybrid electrical vehicles (HEV’s) to the product portfolio. Present research on batteries for HEV’s is mainly focused on lithium-ion battery chemistries, since lithium-ion batteries has the most promising technical potential compared to other types of batteries.

  6. 4. Decision support models for the maintenance and design of mill liners

    Author : Rajiv Dandotiya; Saleh Duffuaa; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Abstract : Mining companies use heavy-duty equipment that work round the clock in highly abrasive environments. Autogenous (AG) mills used in the mining industry and in ore dressing plants are examples of major bottlenecks in the context of downtime and exert an influence on production economics. READ MORE
