RD-E: 5500 Fan Blade Rotation Initialization and Impact
Impacts of rotating structures usually happen while the structure is rotating at a
steady state. When the structure is rotating at very high speeds, it is necessary to include the
centrifugal force field acting on the structure to correctly account for the initial stresses in
the structure due to rotation.
RD-E: 5501 Fan Blade Rotation Initialization shows how to use the /LOAD/CENTRI option in
Radioss to create the centrifugal force field and then apply
an initial and imposed velocity to the rotating fan blades to correctly initialize the
steady state rotating condition.
