Components.IdealRollingWheel ​

Simple 1-dim. model of an ideal rolling wheel without inertia.

Couples rotational and translational motion, like an ideal rolling wheel, specifying the wheel radius.

Matches MSL Modelica.Mechanics.Translational.Components.IdealRollingWheel. This is a re-export of RotationalComponents.Components.IdealRollingWheel.

This component extends from RotationalComponents.Components.IdealRollingWheel

Usage ​

TranslationalComponents.Components.IdealRollingWheel(radius)

Parameters: ​

NameDescriptionUnitsDefault value
radiuswheel radiusm

Connectors ​

  • spline - This connector represents a rotational spline with angle and torque as the potential and flow variables, respectively. (Spline)

  • flange - This connector represents a mechanical flange with position and force as the potential and flow variables, respectively. (Flange)

  • support_r - This connector represents a rotational spline with angle and torque as the potential and flow variables, respectively. (Spline)

  • support_t - This connector represents a mechanical flange with position and force as the potential and flow variables, respectively. (Flange)
