Hi all,
I have a high-temperature system with occasional loads like seismic and slug. since it is a high-temperature line I had to use Snubbers to qualify my system in occasional cases.

As far as I know, snubbers get activated for sudden shock loads with a particular velocity, and in operating cases, it will allow displacement. However, I observed that system frequency has significantly changed after I incorporated snubbers in the model. As I said above, In normal operating cases snubbers will not act as a restraint then how snubbers can change system frequency. Please share your experience.

Regards
SB
