I am trying out a random vibration study in a beam. It is a beam fixed on both ends and a remote mass is defined on mounted hole on the beam.
Input is the PSD curve base excitation. I would like to find the reaction force on those highlighted points bu the value is zero.
Also on the remote mass mounted hole the reaction value is zero for all the natural frequency values?
You can have reaction forces only in the constrained nodes. If you want reaction forces in those nodes, you have to fix them in space so that the displacement is zero.
