Rotational Bearing Friction
Coulomb friction in bearings
Modelica Standard Library
The Rotational Bearing Friction (or Bearing Friction) component models Coulomb friction in bearings, i.e., a frictional torque acting between a flange and the housing.
The τpos parameter is a two-dimensional table (array) that specifies the torque at given angular velocities. Each row has the form w,τ⁡w. The first column must be ordered, 0≤w1<w2<⋯<wm. To add rows, right-click on the value and select Edit Matrix Dimension. Only linear interpolation is supported.
Flange of left shaft
Flange of right shaft
Conditional Support Flange
Optional heat port
Positive sliding friction characteristic
peak⁢τpos1,2 is the maximum friction torque at ω=0
Use Heat Port
True (checked) means heat port is enabled
Use Support Flange
True (checked) enables the support flange
The velocity reinitializes when ω≤ωsmall
Gain driving the relative motion between the friction elements to 0 when locked. This parameter should only be non-zero when using the model with fixed-step integration.
