Applying Bearing Loads

You can apply a bearing load to simulate the distributed force of an imaginary cylindrical surface pressing on an opposing concave cylindrical surface.

To define a bearing load, you specify the magnitude of the vector components of the distributed force.

  1. From the Loads section of the action bar, click Bearing Load .
  2. Optional: Enter a descriptive Name.
  3. Select the geometry supports in the model.

    You can apply a bearing load to one or more cylindrical surfaces.

  4. In the Force X and Force Y fields, enter the magnitude components of the resultant force vector.

    The directional components are oriented in terms of the local feature triad of the bearing load.

  5. Select either Sinusoidal or Parabolic as the Profile.

    The profile defines the shape used to vary the force intensity.

  6. Specify the Angle over which the forces are distributed on the surface.

    Values less than 180 degrees account for a positive clearance, while values greater than 180 degrees account for a negative clearance.

  7. Select one of the following as the Orientation:
    OptionDescription
    Radial All force vectors at mesh nodes will be normal to the surface at all points. This option is generally used for force contact.
    Parallel All force vectors at mesh nodes will be parallel to the resulting force vectors. This option is generally used for specific loads.
  8. Specify the Interaction force as either acting Outward or Inward on the cylindrical surface.
  9. Optional: Enter a Scale factor.
    A scale factor is a multiplier used to scale the magnitude values.
  10. Optional: Specify an Amplitude and Phase angle.
    The amplitude curve defines the magnitude of the feature during the step. The phase angle for the amplitude curve determines the real (in-phase) and imaginary (out-of-phase) parts of the magnitude. The default is 0 degrees, for a completely real (nonimaginary) value.
    Note: Phase angles are available only for a harmonic response simulation step.
  11. Optional: In the field that appears in the 3D area, specify an angle to Rotate about Triad Z.
  12. Click OK.
