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.
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.
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!
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"
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!

OMG!!! Thomas Muller???
Watched zillion videos to understand mode shapes, no one explained it as beautifully as you.
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.

Unbelievably good analogy and explaination !
Not really
Great Analogy

Nice to hear that. The team says Thanks
Explained in simple words! Highly impressed!
Actually it is not that difficult 😊.
Thanks for your feedback
explained fabulously.
Thanks for your good feedback
Sehr hilfreich, vielen Dank.... Thanks a lot
WOW
pretty good
It was perfect

Enjoy!
yes!! thank you! wtf is mode shapes! can no one said the characteristics of the model!
phenomenal job...under rated.
Thanks for your nice feedback. At least you have seen this tutorial :-)
Great video sir..Thank you
:-D so, you are telling me, if I want to get the eigenform of a german, I need to put alcohol inside them?
That is the most common method :-)
Thank you for your video!
super. thank you soooo much.
Really good explained.
The lawn mower works as a good example 😀
Nice explanation.. great job!!
Good job
thank you so much ❤
You are welcome.
awesome video .......... thank you sir
so are mode shapes those point at which each DoF reaches it's natural frequency?
If you mean degree of freedom in the sense of a vibrating mass, then yes. Reality is more complex :-)
Does mode shapes get influenced by stress over the body??
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"
Im quite confused about the theory of dynamic stiffness，hope you could break it down！

how many mode shapes a body can possess?

.. with alcohol
Sir i want to work in field of vibration... May I join u
You are welcome. Follow us on CZcams or LinkedIn. We like to stay in touch.
@@HEADacousticsInternational ... Thank you sir....
If u throw it out of the plane,the person on which it falls will definitely have his/her mode shapes changed
