Centrifugal Load

In one sentence: Apply centrifugal body loads to a rotating structure, computed from the rotational speed and distance from the rotation axis.

Overview

Workbench: FEM
Menu: FEM → Model → Mechanical Loads → Centrifugal Load

Applies centrifugal (centripetal) body loads to a rotating structure. The load is computed from the rotational speed and the radial distance of each element from the rotation axis.

Parameters

Parameter Description
Rotation Axis A line or edge defining the rotation axis
Rotation Frequency Angular velocity in rpm or Hz

Use cases

  • Turbine blades, compressor discs, flywheels.
  • Spinning shafts: hoop stress from rotation.
  • Centrifuge rotors.

Density must be set

Centrifugal load is a body force proportional to mass. Without a non-zero density in the material, the load produces zero force.
