Unbalanced rotor behaviour

[@Hutchy45445]

That's crazy! I've never seen anything that extreme, but it really brings unbalacing into perspective.

[@weenev]

Run 1 was what you should call a static couple unbalance (dynamically unbalanced) Run 2 was a pure static unbalance with no couple component( statically unbalanced but with no couple unbalance) Run 3 is a pure couple unbalance with no static unbalance component.

My senior design team has found this video to be extremely helpful for our dynamic balancing project - we are intrigued by the four vertical metal beams that hold up the actual rotor mount. The beams seem to bend in a single direction but still hold the weight without permanent deformation. Would you mind telling us what material that is and what the dimensions of the beams are? Also, what total weight are they supporting? We are looking to create something similar and your help would be very much appreciated. Thanks.

well, it looks like about 3x15 steel strip, and i would hazard a guess its some type of high tensile or spring steel stock... readily available... i would hazard that the assumed aluminium discs would be close to 750g each... the shaft and bearings, maybe 3kg...

[@vtbhanukiran1231]

Very beautifully demonstrated. Great work. Thank you Sir.

one of my favourite jobs was playing with the rumbler at one place. i would have my hands in that for hours. mess around with the balance weights, change the pattern of the vibrations, the way the media works. could get hard thumping for breaking scale of dirty stuff, or soft gentle figure 8 (analemmas, get it right) motion for polishing... or nothing at all :) one aspect totally unrelated to this video but just as fascinating was the abrasion, the amount of wear that took place. my god. steel lasted for literally hours in there. had one "pet" chunk of carbide from when i started to when i left, watching as it slowly dissolved... three years!

Congratulations for that very clear model to explain unbalance.

[@mosialive]

Wow. Thanks for the demonstration.

So that earthquake in here in Japan was YOUR FAULT! Expect to hear from our attorneys....lol

[@colt4667]

Very nice demonstration !!!

Nice video. Regarding the characterization (static, dynamic unbalance) not only the amount of weights, but (and most importantly) the rotor layout has to be considered. Here we have both our discs outside the bearings (sort of double overhung), thus a single weight is enough for causing dynamic unbalance.

thanks for the demonstration.

Hello, Jacques. Could you tell me where I can find more about this model of Vibration Testing Bench? I'm very interesting on building one of that. Thanks.

[@timsonsengineeringltd2164]

Nice demonstration of different types of "out-of-balance". May I link to your video from an article we are preparing about dynamic balancing?

[@vishalmane6602]

realyyy good example......................................................

[@gerry6691]

came to find out how vibration motors in vibration feeders work!

[@ziruiliu3998]

really good demo,thank you

[@jacquesmaurel]

Glad you liked it!

[@med.yahyanouh8890]

really interesting so how can i find more about the type of vibration , i need them to prepare practical works for students

[@primodernious]

you can probably run this thing with a bell as well.

[@BHARGAV_GAJJAR]

Very nice demo

[@meckanikai1097]

Anyone with any mathematical models or formulas for these kind of systems? I'm looking for some solid comprehensive scientific sources.

[@pneumatic-generator2022]

nice demo thank you

[@asetyabudy9915]

How much force and work output of sentrifugal can it produce??

[@مهندسأحمدعبدالعظيم]

Amazing

[@fidelcatsro6948]

explains why we should only drive Lexus cars!

[@jacquesmaurel]

No problem.

[@박병희-w4b]

Thank you!!

i need anlysis plz ??

quotation req

[@tawonsingosari1211]

🙀👍

[@bitankumarnayak8528]

Power sources of rotation not shown clearly, Worst video

[@ravanabrahmarakshas4263]

very bad rotors. all go to hell. :)

[@fidelcatsro6948]

only enfield bikes in india make good rotors...
