Hello everyone,
I'm a student and I'm trying find the natural frequency of a flexible cantilever beam. For the model, I used a box as the body and then used the Fixed connector at one end of the beam. After that I tried to make the beam flexible. I used the Rigid to Flexible body option for that. I selected Aluminum as the material and then clicked on OK without getting to the advanced settings. After that I went to the simulation tab and after finding static equilibrium, I computed the linear modes with damping. Now I have two questions:
1- Why are the results wrong? whatever I do, I don't get the correct natural frequency. I have experimental data and the results do not match!
2- In the model tree, All Other, Materials branch, I can only find Steel! I have selected Aluminum as the material, why is it steel in the materials branch?
Thank you for your time.
