dampening pump skids to reduce resonation
Registered Member What is the vibration frequency of the vertical motion on the I-beam skid? Does it make the speed of the pump shown or something else that shares the skid? Is there a lot of pipe motion as well? Did you inspect all pipe supports and hangers? A 2-step approach could be considered: 1) Epoxy grout under I-beams (possibly raising about 1/2" or more to get suitable grout thickness along with epoxy-set anchor bolts. 2) Cement non-shrink or epoxy (preferred) grout to fill entire I-beam skid frame. [ more ]
Registered Member That's the ultimate fix which we discussed for all the pump sets originally with the client in regards to their loss of motors and pumps. It is a history of mechanical repair including alignment, sanding down diameters of shafts for interference fit instead of heating coupling bushing in oil bath [ more ]
Registered Member Considering the obvious (at least to me) problem the movie shows, I am not at all surprised of the history. This could be a classic case history of fixing the root-cause problem to solve all the issues noted. Time will tell Please keep this forum informed of what you find as you go forward.

ME Scope M# Links
Registered Member Hey Jim, Yes... they matched. I have actually modeled this installation in another ODS software (Clear Motion) before and now that I have an ME Scope license I only modeled a portion of the installation so I actually have more data than I need. By importing that extra data which didn't match any points, it created the error message. Was a good learning experience. ME Scope software is so powerful.... amazing tool to have. Glad I have a license now. Thanks and have a good weekend, KB [ more ]
Registered Member Good to hear. I've done that myself. I try to learn by my mistakes and, if that were true 100% of the time, I would be really "smahht" by now BTW - Did the points/M#'s in question start with where the error code began? J [ more ]
Registered Member So I found out that this actually wasn't an error, and it wasn't killing my animations. I was bringing in data in the data block that was not assigned to a point.... this created the error message. When I ran my interpolation calculations for each substructure, everything worked out fine. Animations looks great now. Thanks, KB [ more ]

coherence measurement
Registered Member thanks dear dave for useful information [ more ]
Registered Member http://www.calpoly.edu/~cbirds...ng%20%20Analysis.pdf Top of page 11 Think of it this way, you are comparing two signals and you want to know if the frequency on sensor A is the same as sensor B. IF the frequency is the same coming into both sensors then there should be a coherence value of .95-1.0.....IF the frequency is not the same then coherence could be from .6 to 0..... An indication of a natural frequency in an FRF plot would be a peak present at a given frequency, and at that... [ more ]
Registered Member Sure, you can do a transfer function of slid (did you mean skid?) compared to pump housing. Coherence is a measure of causality between input and output. Let's say you measure the COH = ~1 between the ?skid? and pump. In this case, the relationship between the two are the same but not sure what useful information that gives me or whether it helps me figure out the problem. As Gary stated, it is used primarily in impact/modal testing to provide confidence in the cause/effect (e.g. impact to... [ more ]

Vertical Pump - Modal Analysis
Registered Member I have done this type of testing on large vertical pumps, but not with ME-Scope. Water inside and outside the pump column adds mass. A rule-of-thumb is to use twice the volume of water inside with same sump level to account for the mass of water outside the column. There can also be a difference in natural frequencies with the impeller support conditions between wet and dry. Pray that the stop logs hold back the water when you are standing knee deep in water, muscles, and gunk while... [ more ]
Registered Member Hi Jim, Thanks for looking at this and replying. I will most certainly look into the mass of water/ME' Scope issue. I am curious about this as well. The guy we've hired to do this testing is one of the best at Modal/ODS that I know of and has years and years of experience so I am the results we will get are as accurate as possible. Like you said, we will be using a combination of coast down testing, ODS, and Modal data to try to narrow down where those frequencies are and how much they shift... [ more ]
Registered Member If I'm not mistaken, Vibrant Technologies has a version of MeScope that allows the user to input variables (e.g. mass of water) and make assessments of what you are looking for. You might want to contact them directly. For the modal test, are you impacting above ground and obtaining response data from the support column below ground? I've not done that but would be very curious how well the data comes out. So when the ODS is performed (now there is the added mass of the water in the wetted... [ more ]

Impact test on Base plate
Registered Member Hi Nicolas, I like Jim's post here with regard to your question - in particular 400 lines of resolution being applied - definitely more than enough resolution and huge time saving. For baseplates and larger surfaces I have use a small fractional hp variable rpm d/c motor. I have a fly-wheel type rotor fitted to the shaft with a known amount of unbalance weight to create vibration. I place the motor in position - secure it and begin tuning (via attached rheostat controller) through different... [ more ]
Registered Member regarding the impact test, spend some time bumping the machine in different locations while moving the accel. Watch the response in all three axis and eventually you will be able to determine a good driving point for the entire test. Once you find the driving point that excites all your measurement points in each planer you can use that for the fixed location. I usually use 400 lines for a 200hz fmax. that gives you frequency resolution of 30 lines which is more than adequate resolution and... [ more ]
Registered Member Reciprocity is a true property. After all we measure magnitudes ratio and relative phase. I prefer to use roving accelerometer for the following reason: one wants to make sure that he is NOT impacting a node prior to the test. Once you have verified that it is not the case and you ARE in fact inparting energy, you can proceed with the test. Fixed impact location also is convenient to ensure that direction of impact has components in all 3 axes. [ more ]

Nodes and Anti-nodes
Registered Member you want to place a brace at an antinode. determining which bending mode will come down to the frequency at which the component is vibrating. If you have determined there is 3 bending modes on a pump discharge pipe. Say the first is at 1700cpm, the second occurs at 2250cpm and the third at 3890cpm. The motor driving the pump is on a VFD and has an operating range from 1500 to 1785RPM. Measured vibration on the pipe is highest when machine shaft speed approaches 1700RPM. In this case the 1st... [ more ]
Registered Member Changing stiffness, mass, or damping at a node point would not significantly affect natural frequencies or vibration levels at that point or other parts of the structure. Walt [ more ]
Registered Member The word "node" is a corruption of "no displacement". So there is no movement at a node. Therefore there is not going to be a benefit to making a change (other than perhaps a mass change) to a node. Best regards, Tom Murphy [ more ]

vibxpert and ODS
Registered Member I have been using the Vibxpert to complete ODS and Modal projects in MEscope for a few years. I have used this on mostly pumps and motors and their supporting structure. Some of the larger project required several hundred measurement points. I have used the current line drive accelerometers that come with the VXP and aftermarket ICP accelerometers receiving good results with both. Since the device is only 2 channels it takes a while to complete data collection. X Y and Z has to be recorded... [ more ]

structure health monitoring
Registered Member Structural Health Monitoring is monitoring a structure (like a bridge, building or dam} for changes that may indicate damage or degradation of that structure. While the structure is static, it is subjected to dynamic forces; wind will blow over the bridge or against the building, waves will hit the dam or oil platform, cars will also drive across bridges. These dynamic forces will excite vibrations in the structure. The forces excite modes of vibration in the structure and Structural Health... [ more ]

How can we use Poor man ODS with CSI2115 single channel analyzer
Registered Member CsI 2115 can collect Phase data , i have not used but we have the option Phase analysis in our instrument . could you please explain the procedure step by step . [ more ]
Registered Member My understanding is that the CSI-2115 analyzer can measure shaft speed and phase. Here is a link to an old paper describing the 2115 for balancing: http://www.osti.gov/scitech/biblio/552750/ Kishore, if the vibration frequency of interest is at 1x shaft speed, then you can do ODS test with 2115 by measuring shaft speed (tachometer connected to BNC on analyzer) and vibration amplitude filtered at 1x shaft speed. I use Excel Scatter Plot to make scaled X-Y plots of vibration amplitude and... [ more ]
Registered Member If I recall correctly, the 2115 will not collect phase data, just velocity and peakvue. You need to have an analyzer that has the ability to collect phase data with a strobe/photo cell/laser/2nd channel as the trigger Dave [ more ]

Modal Analysis Test: on a "fixed" or "free body" rotor
Registered Member As I surfed the literature, it appears that during the modal test one would want to replicate as close as possible the actual operating conditions of an object. For instance, an aircraft should be suspended using soft ropes; on another hand, a heavy impeller should NOT be tested in soft suspenders, but rather with the shaft in the bearings which approximates fixed points condition. The softness of the ropes and stiffness of the attachment should meet certain condition for accuracy, of course. [ more ]
Registered Member You can find a brief entry in Hartog's book on vibration. Campbell's paper uses it. [ more ]
Registered Member Thanks guys for your responses. No, I am not doing an EMA in order to compare the results with FEA. I think EMA can stand on its own. I would like to use EMA to prove that the crack pattern developed in the impeller is due to the excitation of a specific modal frequency. The drawback of an EMA test however is that it is static. A non spinning impeller will have some modal parameters affected by additional stiffness due to spinning. I guess Southwell's Theorem talks specifically about that. [ more ]

Glued Structure for Modal Analysis
Registered Member I totally agree with Testtech. If you picture a structure in 3D as series of interconnected mass-spring elements and assuming that glue vs. metal element stiffness are drastically different, it will become clear that modal parameters will also be different. To verify this concept, you can do a quick modal test on a metal bar; then cut it, glue the halves together using, say, locktite glue, and test again. I predict hugh difference. [ more ]
Registered Member Seems unlikely. I guess you have to believe that the elastic modulus of the glued joint is similar to that of the solid metal. Do you have reason to believe that? [ more ]

Modal test: together with the shaft or impeller alone?
Registered Member Ron, Performed modal analysis on impellor with the shaft. Animation looks stunning. If interested I can email the avi file to a private address. [ more ]
Registered Member Dave, If your major concern is the tiny raised blades on a high speed wheel, the influence of the shaft is probably insignificant. If you care about the modes of the wheel itself, 1D, 2D, etc. then the shaft is necessary. I would still do all testing with the shaft since it is the true platform the impeller will work from.

Registered Member Hi Gary, I might have misread your question, but there is an option for 'cross spectrum' in ME'Scope trace window.

Mescope newbie
Registered Member Thanks for that Dave, I have read a bit further on and can see how this relates. [ more ]
Registered Member Yes, HVA or XYZ at each measurement location. While standing at the back of the machine, looking toward the machine, the right hand side is positive and the left hand side is negative, depending on how you mount your sensor. So if you collect Z and the sensor is pointing away from you call it positive Z, while standing in the same location and the sensor is pointing toward you then it is a negative Z. Dave [ more ]

Registered Member Hi Josh, if you are using "relative" in a geological term, then perhaps yes. I have read documents dating back 50 years using this technique. I first put my hands on software for this in 1988 - then using an HP300 series computer with an IEEE interface to a spectrum analyser. The hardware took a leap forward about 4 years later and the only real changes since then seem to be just at the edges. It is an extremely useful tool and I have helped baffled engineers solve many problems with it. Tom [ more ]
