Hi there - new user to SUMO and all :) I have been reviewing the implementation of the electric vehicle model as detailed http://sumo.dlr.de/wiki/Models/Electric, and I'm slightly confused as to the definitions of a couple of the parameters as listed.
Jint 'internalMomentOfInertia' & Crad 'radialDragCoefficient'. I have some reading on inertia components, but I am trying to understand if this 'internal' rotating elements includes all rotating vehicle elements (i.e. shafts, motor and all vehicle tyres)? If this is the case then I'd say figures for 12m length transit buses are in the region 30-50kg/ m2 if that seems correct to others? I have never come across Crad: radialDragCoefficient before & am struggling to understand exactly what this represents. Any further description/ definition? Is this the aerodynamic drag of the rotating wheels (as being different to rolling resistance coefficient & vehicle air drag coefficient) or something else? I was reading one of the SUMO references and it is briefly described along the lines of centripetal force Fra & curve resistance coefficient Crad...I really am missing something. Many thanks for your time & any clarification that can be provided. Kindest regards, Colin ------------------------------------------------------------------------------ _______________________________________________ sumo-user mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/sumo-user
