Hello All I am trying to model a damper in MSC Nastran. I do have damper curve (force versus velocity) for compression and expansion. Please tell me how to proceed with the modelling of damper for given property curve. Thanks Sumit Sheoran

Hello Vivek

Thank you for your immediate response. After studying about PBUSHT, I came to know that it requires force per unit velocity versus frequency table. I only have force versus velocity curve for damper and no frequency info is available with me. I am trying to run a modal transient analysis for full vehicle which includes damper behavior.

So is it possible to define the damper using force versus velocity as input ?

Regards
