2. 1. An Investigation of the Iron-Ore Wheel Damages using Vehicle Dynamics Simulation

   Author : Saeed Hossein Nia; Sebastian Stichel; Matti Rantatalo; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; three-piece bogie; wear; RCF; prediction; traction; braking; heavy haul; simulation; Vehicle and Maritime Engineering; Farkostteknik;

   Abstract : Maintenance cost is one of the important issues in railway heavy haul operations. For the iron-ore company LKAB, these costs are mainly associated with the reprofiling and changing of the wheels of the locomotives and wagons. The main reason for the wheel damages is usually surface initiated rolling contact fatigue (RCF) on the wheels. READ MORE

4. 2. On Heavy-Haul Wheel Damages using Vehicle Dynamics Simulation

   Author : Saeed Hossein Nia; Sebastian Stichel; Carlos Casanueva; Per-Anders Jönsson; Ernesto Garcia Vadillo; KTH; []
   Keywords : wear; RCF; rolling contact; traction; braking; heavy-haul; FASTSIM; FaStrip; Vehicle and Maritime Engineering; Farkostteknik;

   Abstract : Maintenance cost is one of the important issues in railway heavy-haul operations. In most of the cases, these costs are majorly referring to reprofiling and changing the wheels of the locomotives and the wagons. The main reason of the wheel damages is usually severe wear and/or surface initiated rolling contact fatigue (RCF). READ MORE
