Dear,

My client request me to solve his problem that is Vibration in big piping system form 2 phase flow. (I surely 2 phase flow is cause)
But I really don't have experience about dynamic analysis. Could you please suggest step by step to analysis this problem.

I simply try to use Modal Analysis in CAESAR II to check the Natural frequency of system. What frequency do we consider? Or I lost??

The others question, I really interested in Dynamic Analysis and need to find source of information or standard. Where can I find that?

Thanks

This has been discussed on this forum frequently. You need to do a Harmonic Analysis, so use the Search function on Harmonic and you will find discussions of this.

This is a questions that has been asked many times in this discussion forum - please learn to use the search function at the top of this page (find the "post a poll" button and just below it in the middle is the "search" hypertext). When you use the search function you can read all the wisdom of the many people who contribute to this forum. Also, you should go to the COADE "Mechanical Engineering News" site and download and read all the past issues as they present a wealth of practical piping engineering. (I love "cut-and-paste).
