Example 23: Deformation due to Centrifugal Force

General

• The deformation due to the centrifugal force is analyzed.
   

• The deformation, the displacement distribution, and the stress distribution are solved.
   

• Unless specified in the list below, the default conditions will be applied.

The Angular Velocity tab is set as shown below.

It is equal to 100 rotations a second.

Tab	Setting Item	Settings
Angular velocity	Z component	360X102 [deg/s]

Model

If the angular velocity is opted, the rotational axis is Z axis. Therefore the model is created to be symmetric with reference to Z axis.

Cylindrical solid bodies are created and they are modified with boolean operations.

Results

The Z-direction displacement is shown below by contour. The contour diagram shows the magnitude of displacement.

The non-supported portions of outer wheel deforms outwards.

 

The vectors of the stress are shown below.

The tensile stress is generated throughout the model, concentratedly generated at the supporting portions.
