Looking for information related to creating a superelement using Component Dynamic Synthesis (CDS)
I am interested in creating a superelement that can be used to repesent a transfer function of a plastic bracket / rubber bushing dynamic response to be used inside a Optistruct system model. Steady State frequency domain analysis is the solver method being considered. Small amplitude linearize model with direct integration is acceptable. Long term modeling goal would be to capture the anistropic material frequency dependencies for both the stiffness and damping material properties at the element level. The plastic bracket mold flow analysis will be done using Digmat / Mold Flow Software. I have researched and found an article on using CDS as compared to the CMS method for superlement creation. I am interested whether CDS could be a better approach as compard to CMS for capturing a more accurate damping characteristic for every discrete frequency in the range of interest. If anyone has experience on this topic, I would interested in connecting to discuss further. Thanks Marc
