Reply To: Tuned Mass Damper on a simple supported beam APDL script

To add to what Claudio said you can do all what you want, natively inside WB Mechanical, using combin14 for spring and mass21 for mass.

1. You need a freestanding remotepoint at the mass location.

2. Define a point mass using remote points on the above defined point/location (this will be the mass21 element)

3. Finally define a spring connection using the remote point for the mobile (spring def.) the remote point and a node or if you have a vertex on your beam element for the reference side (spring def.). This is the combin14.

 

So we should have in our Mechanical tree, 1 remote point (free standing), 1 point mass (under the geometry tree), and one spring (under connections).

All the best
