Shaft with Torsional and Transverse Flexibility

This example shows two flexible shafts that have torsional and transverse flexibility. One shaft computes transverse motion using computed eigenmodes, and the other shaft uses a lumped parameter approach. The boundary conditions on the shafts can be changed on the block masks.

Model

Computed Eigenmodes

The plot below shows the eigenmodes computed automatically from the physical parameters of the Flexible Shaft. Alternatively, precomputed eigenmodes can be entered directly as block parameters.
