AI Thread Summary
An underplatform damper is a component used in rotating machinery, particularly in applications like steam turbines and jet engines, to reduce vibrations and enhance stability. It functions by dissipating energy and minimizing the effects of dynamic forces on the machinery. The discussion highlights the need for a clearer understanding of this component, especially for those transitioning from structural engineering to more dynamic fields. Participants seek intuitive explanations rather than purely mathematical descriptions to grasp its significance better. Overall, underplatform dampers play a crucial role in improving the performance and longevity of rotating systems.

Can you expand a bit on your question? Where have you heard about this component? What do you mean by platform? What kind of platform? What do you think an "underplatform damper" would be used for?

I guess the OP means something like
http://web.itu.edu.tr/sanliturk/Publications/GTP00919.pdf

There are many of variations on this basic idea used in rotating machinery like steam turbines, jet engines, etc.
 
Yes, AlephZero- that's exactly what I was talking about.

Reason is, I have done consideerable finite element coding related to dynamics/vibrations -however recently I have been introduced to terminologies/components involving jet engines in general.I'm mainly a structural engineer.

Therefore, was getting into foums/weikepedia and getting a feel of terminologies.

I was looking for someone to explain me this in an intuitive way so that I can expand my thought process than being just mathematical.

Sorry berkeman if question was unclear.

Please can anyone help further - i.e.an intuitive way of undestanding the function of underplatform damper?
 
Please can anyone help?
 

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
