Hi misu_bhowmick,

 

Please let us know what data you have?

 

Do you have Time load data?

 

In that case, you have to convert the time signals to FFT and FFT to PSD. Please see the attached files.

Hi,

 

Yes, Go to Utility browser>>Create Table>>TABRND1>> import file to get the PSD data.

 

Make sure the file format is any of the supported formants (.txt, .dat, .csv)

I have one more query; i have FFT data  of  acceleration time signal on different locations of IP (instrumental panel).

How to use this data in modal frequency response (MFRA) analysis in Hypermesh?

 

Thanks in advance.
