BHA Dynamics Analysis

20 June 2019 Hello everyone,

I am a PhD student working on BHA dynamics this period

While you are doing a BHA dynamics, how you can understand if you will have vibrations from the simulation results?

I am getting the following:
Resultant stress, shears force, axial force, stress components, etc.

From the graphs I can understand where we have the higher stresses, but where is the point that you will observe vibrations? For example a shear force of 2600 lbf..what does it tell me?

I know that every BHA and drill string is different, but i want to know the principle on this..

Regards,
Alexis
