Rolling Resistance

Maplesoft.1DMechanics.Translational.FrictionStop.RollingResistance

	Description
	The Rolling Resistance component models the resistance of a rolling wheel, dependent on the vertical wheel load (due to gravity), inclination, and rolling resistance coefficient. $flange.f = C_{r} f_{Weight} \cos (α)$

Variables

Name	Units	Description	Modelica ID
$s_{rel}$	$m$	relative distance	s_rel
$v_{rel}$	$\frac{m}{s}$	relative velocity, flange A to flange B	v_rel
