How can I apply Fatigue Analysis combining Modal Stress Results(.h3d) and Modal Participation Factor result(.dac or rpc file) taking from Adams Car for FLEXbody scenarios ?

Omer Faruk GUMUS_20556

I would like to Fatigue Analysis with linear superposition approach using modal stress results[.h3d] from FEA and Modal participation(modal coordinates) results[.dac or .rpc] from AdamS car or any other Vehicle dynamic Tool. These method can be directly perform in .ncode or FEMFAT software, but in Hyperlife using Time Series or Modal Superposition methods does not allow to import either .h3d Subcases in Time Series or .dac formats in Modal Superposition. Is there any way to do such fatigue analysis?

Hi,

At this point we only support .pch format for the Eigen Value - as you may have noted from the GUI. I will bring your question up with development.

Thank you

Hi Omar,

HL currently supports PCH and MRF formats, as the documentations states, but can Adams export PCH format?

We'll create an RFE to make note of the formats you'd like to support. Could you share any sample .dac or .rpc files with us for the RFE?

Thank you
