Hi Hamderson,


 


It is usually a long and iterative process to match the simulation with the experiment and there is no guarantee. There are several questions I would ask myself when I see a mismatch from the experiment:


 


1. Does my simulation represent the experiment setup well? For example, are there any extra mass I need to add to the model? In the experiment are all the components "perfectly bonded" like the model does? Are my material models


2. I would also plot and play the deformed shape to get an idea of how the equipment deforms under each frequency. That may also provide some insights into what may cause the mismatch. 


 


Regards,
