Hi Subham, there is a rigid element with a central node representing the base that connects to the launch adapter. This node has 2 constraints: 1) Enforced motion location for the 3 translational DOFs, 2) User-defined constraint with all 6 DOFs fixed. The input PSD is complex due to the notches, you can get it here: nextcloud.mayahtt.com/index.php/s/dAbwL7fdi4JqnsX . Generally speaking, once you enter the XY function manager from the Edit Translational Nodal Excitation dialog, you can create a new PSD function as follows: Click on New, then under XY data create, click Key in from text editor, and enter the PSD as pairs of (frequency, PSD) where the PSD is in g^2/Hz.
@@philippetremblay3140 Hi Phillippe, apologies for the delay in response. Thank you so much for your reply. I have a few concerns, why do we need to constrain a node and not the entire adapter as a 3d part? I have a set of PSD values, how can I use those PSD values?
What are the constraints you used? And how do I input the PSD values myself if I don't have the AFU file?
