Introduction to modal analysis | Part 1 | What is a mode shape?

[@mrugeshpatel6804]

OMG!!! Thomas Muller???

[@gayatrigore7866]

Watched zillion videos to understand mode shapes, no one explained it as beautifully as you.

[@HEADacousticsInternational]

Zillion is a really impressive number :-)
We are all the more pleased that we were able to explain this complex topic in an understandable way also.

[@lioneloddo]

A definition of modes based on linear algebra theory is so much much more satisfaying! A mode is just one axe, one dimension of an infinite dimension space. It blows the mind to realize that there is complete analogy between a 3-D dimension space and a modal space. To imagine a stationnary wave as one axe of a basis is just unbelievable, but it's true. Teh imagination can't accept this analogy, but using mathematicz, we can see the perfect analogy in particular the orthogonality property.
In 3d-space, what is growing, it's the length of th (x,y,z) -axis for example, but in a modal space, what is growing, it's the amplitude of the specifics waves.

[@pathakan1988]

Unbelievably good analogy and explaination !

[@QwertyCanada]

Not really

[@chinmaya1765]

Great Analogy
Personally I may not agree in some point regarding the properties and other definition but I will definitely prefer and use the similar analogy for explaining others. Thanks to the team for providing complex knowledge in simpler form.

[@HEADacousticsInternational]

Nice to hear that. The team says Thanks

[@muhammadaliabid5793]

Explained in simple words! Highly impressed!

[@HEADacousticsInternational]

Actually it is not that difficult 😊.
Thanks for your feedback

[@THEHALMIORIGINAL]

Really good explained.

[@jccasava2035]

Sehr hilfreich, vielen Dank.... Thanks a lot

[@muhammadnihalnaseer8713]

explained fabulously.

[@HEADacousticsInternational]

Thanks for your good feedback

[@andrewbeshara4306]

phenomenal job...under rated.

[@HEADacousticsInternational]

Thanks for your nice feedback. At least you have seen this tutorial :-)

[@chetanfulaware]

Great video sir..Thank you

[@pushkarlohiya834]

Nice explanation.. great job!!

[@user-cy2pr6yn7s]

WOW

[@taoyin2071]

Thank you for your video!

[@mihirborker5240]

pretty good

[@muhittinselcukgoksu1327]

super. thank you soooo much.

[@manjunatham_s]

Good job

[@user-kh1jv5jk6n]

It was perfect

[@HEADacousticsInternational]

We're glad we could help you get started.
We have many more videos here that will help you overcome the typical difficulties in understanding modal analysis.
Enjoy!

[@shwetanshumala2151]

awesome video .......... thank you sir

[@nivperry685]

yes!! thank you! wtf is mode shapes! can no one said the characteristics of the model!

[@alexbalzer31]

:-D so, you are telling me, if I want to get the eigenform of a german, I need to put alcohol inside them?

[@HEADacousticsInternational]

That is the most common method :-)

[@aweiwei1987]

Im quite confused about the theory of dynamic stiffness，hope you could break it down！

[@HEADacousticsInternational]

Indeed, this is a confusing topic. :-) Here is our solution:
On the 8th of October there is a free online seminar about Transfer Path Analysis (TPA) which will explains this topic in total. Just search for "HEADucation" and register for this seminar. You are welcome!

[@arshianikbakht1020]

thank you so much ❤

[@HEADacousticsInternational]

You are welcome.

[@ignaciomarre7398]

so are mode shapes those point at which each DoF reaches it's natural frequency?

[@HEADacousticsInternational]

If you mean degree of freedom in the sense of a vibrating mass, then yes. Reality is more complex :-)

[@viharize]

Does mode shapes get influenced by stress over the body??

[@HEADacousticsInternational]

Yes, this effect exists. For example: Components that have not been hot-annealed again. This can cause considerable detuning of resonances in sheet metal parts. Look for "residual stress"

[@jay22kar]

.. with alcohol

[@jayaghosh_]

how many mode shapes a body can possess?

[@HEADacousticsInternational]

Thanks for your comment. Please write an email with your contact data to [e-mail] and we get in contact with you soon to provide you with detailed information on your question.

[@trikal8949]

Sir i want to work in field of vibration... May I join u

[@HEADacousticsInternational]

You are welcome. Follow us on UA-cam or LinkedIn. We like to stay in touch.

[@trikal8949]

@@HEADacousticsInternational ... Thank you sir....

[@Feisabeilillah]

If u throw it out of the plane,the person on which it falls will definitely have his/her mode shapes changed
