How to set deck using hm and how to do TPA analysis visualization in hypergraph

Hi,

HyperGraph 2D has a Transfer Path Analysis (TPA) utility which identifies the complex contribution of the excited structure through attachment points to a response in the responding structure.

 

You can refer to our online help to get detailed information on TPA just by searching the keyword 'TPA' as shown below in thumbnail.

 

Attached is the zip file containing representative input deck, document from online help on various NVH Post-processing utilities.

 

I hope this helps, do let us know if you need any further information.

 

Regards

Hi,

 

Please refer NVH utilities document of Hyperview to carryout order analysis.

CSV file for Tabled1 cards contains  Frequency vs load history.Normally analyst get this test data from testing team in txt or csv format.(It could be frequency vs load,velocity,accelartion & displacement)
