17 Jan 2020 Cyclic Symmetry
Cyclic Symmetry is a type of symmetry used in a simulation to simplify the FE model.
Cyclic symmetry is appropriate when the geometry, loads, constraints and results of a partial model can be copied around an axis multiple times to create a complete model. The surfaces selected for cyclic symmetry must also map to one another for cyclic symmetry to be appropriate.
Examples of objects that can be simulated using cyclic symmetry are propellers, rotors and wheels. If the loads on one propeller blade, for example, repeat, then only that one blade needs to be represented in the FE model, rather than the entire hub of blades.
In Cyclic Symmetry, the forces and loads applied will be equal on both sides/faces of the section used in the model. The model also needs to be statically stable in all 6 directions, as cyclic symmetry being applied does not prevent movement or displacement in the tangential direction and hence must be constrained otherwise.
