Hi Thank you for the Video. I thought of exploring more on this but am facing problem with the syntax. Can you please share us the staad model. Thank you
I got it, now it’s flawless. Thank you. I need one info. Suppose I am designing a dynamic pump skid. Can I ignore transient effect . ? Since in the above example we are Taking steady state and ignoring transient effect.
@@prajwalbm9508 transient part is in the initial phase of the vibrating motion. Very quickly it decays depending on the damping of the structural arrangement. In case you want to check the transient part too then use the THA. You may create the time vs acc pairs in spreadsheets from the speed zero upto certain speed ( till you can assess the decay of the transient part) and feed these values in time history definition and perform the analysis.
@@Torq123 Thanks for the quick response. I performed time history harmonic analysis for my skid (Displacement against time). As u told for initial fraction of seconds my displacement are high. (>1 in) later in steady state it’s around 0.7 in, but my skid spring capacity is 1 in. I am bit confused here.
@@prajwalbm9508 there could be two reason . (1) transient component is significant (2) the natural frequency is very close to the operating frequency at the start ( natural frequency is low)..
Hi thank you for the video. But how to interprate the result from steady state analysis? could you explain it, how to determine either our structure not resonance due the vibration from the machine. Thankyou
Thanks for your comment and this is indeed an pertinent question. Please see my webinar in this where detailed discussion was made . Hope you could find some help from there. ua-cam.com/video/HjZBvYfXOkM/v-deo.html
