modelRollingResistance
Constant force changing sign with speed, multiplied by cos(atan(inclination))
Extends from Modelica.Mechanics.Translational.Interfaces.PartialForce (Partial model of a force acting at the flange (accelerates the flange)).
Information
Model of constant force which changes sign with direction of movement, mulitplied by the cosine of inclination angle.
Please note:
Positive force acceleractes in both directions of movement.
Negative force brakes in both directions of movement.
Around zero speed regularization avoids numerical problems.
