Fluid Film Bearings Video Lecture | Design of Machine Elements - Mechanical Engineering

[Music]
hi there my name is Jason Tranter the
founder and managing director of Novus
Institute and this year in the Dubai
conference I'll be delivering a half-day
workshop entitled an animated
introduction to fluid film bearing
vibration analysis so what will I be
talking about I will start discussing
the measurements themself just to really
clarify how proximity probes work how
the key phaser worked how its installed
and so on and we'll look at phase and a
little bit of heavy spot and high spots
although we'll get into that a little
bit later then we'll talk about the
analysis tool so really clarify what is
the orbit plot and what does it tell you
the centerline plot full-spectrum plot
bode plot polar plot so we'll go through
all of those and using some case studies
and so on and really make sure it's
crystal clear what those plots are what
they tell you why you'd want to use one
over another and and so on we'll talk
about the bearings themselves what the
differences and the different types of
designs and a little bit about rotor
dynamics it really helps to understand
rotor dynamics if you're going to
understand what these plots are about
understand the phase readings understand
balancing and understand the fault
conditions because we will also talk
about the fault conditions unbalance
preload looseness misalignment rubs oil
whirl and and oil whip now if you've
ever been to one of my workshops or
listened to a webinar or something like
that you'll know that we have lots of
animations and simulations that make all
of this much easier to understand you
may look at those lists of topics and
think oh gosh YZ need all week to cover
them now we do have courses that do take
all week that you know get into a lot of
depth the fact is with these sorts of
animations and simulators we can cover
quite a lot in a short time to give you
a really good idea of what
it's all about in half-day workshop
we're not trying to turn you into an
expert but boy you'll learn a lot it's
information you can take away with you
if you work in that in that field you
know we'll talk about how orbit plots
are developed both in terms of the
measurements themselves and you know how
that works and the probe orientation and
and these sorts of things but also you
know what does the information actually
tell you about the machine which you'll
see in just a minute here in one of our
many many animations I've only just
shown a few of the animations here we'll
talk about rotor dynamics as well and
the bending modes and the various notes
anyway I will talk about the orbit plots
we've got so many simulators you'll see
you'll see a whole lot but in case
you're wondering what a simulator
actually is they're just interactive
graphics and I can you know choose
options to slow it down turn on its
batard with this touch screen TV see if
I can get that to work there you go turn
on the proximity probe and on the key
phaser and I can turn the knobs to
change the shape of the orbit I can do
lots of things anyway to explain what's
happening with orbit plots and all of
the measurements that involve proximity
probes
you know what the time waveform looks
like what happens if the probes are in
different locations or the keepers in
different locations we can talk about
orbit data waveform data the full
spectrum response plots you name it we
can explain it and illustrate it with
these really useful simulators here's
the center line plots if you wonder what
a center line plot is you know we start
with the orbit you think about what the
orbit really means but then what does
that actually mean in terms of the
bearing well there's the shaft moving
like that and there is if you like the
journal within the bearing and the
bearing has certain clearance which are
indicated there and what that means is
that I can't move that the journal
outside of that clearance and that's
what the plot tells you about
and I'm not sure how much you can see
through the movie but that's the sort of
thing we'll be doing in the class to
make all of this stuff more interesting
but more educational so that you
remember it and understand it are we've
also got these plots to talk about mode
shape surface life stiffness in the
bearing versus heavy stiffness in the
bearing and how does the how does the
modes shape change anyway all these
things are there to make it more
interesting and more understandable and
it's worth saying that in October we
will be running a category 4 course in
Dubai and there's a lot of distance
learning that goes on beforehand so it's
not something you want to wait till the
last minute to register for sure but
this workshop will both give you an
indication of what the training style is
like but also give you a feeling for
whether you're ready for such a course
anyway to be an fantastic course lots of
movies online that you get to see at
your leisure and you can see them over
and over again and then of course you
can go to the course and we do a
refresher on everything anyway that's
what I'll be teaching at the Dubai
conference and maybe at the other
conferences we haven't decided yet but I
really hope to see you at one of the
conference's in Dubai Antwerp in Belgium
Surfers Paradise in Australia
Orlando in the United States I hope to
see you there
