Structure borne noise in train car using Femap/ Nastran


Hello Community,


I have Femap to work with. I have to model the interaction of a train with the rails and predict the noise levels inside a car. Assume that I have the loading function.


I've done modal analysis with Femap yet, and static analysis. However, I am completely new to this kind of a problem.


I would greatly appreciate any help/ pointers in this regard, starting with opinions on whether it is even possible in the first place.


Thank You
