I watched this video for thousand time is very simple and easy to understand if you quite familiar with the theory part of 2Dof damped system thank you a lot sir great effort
Thank you Sir. I am a brazilian student of electrical engineering and i am studying subsynchronous resonance. I have to do the eigenvalue analysis for a spring mass model with 6 mass . I have all spring constants (K) and Inertia Constants (H). Instead of M, in your anaysis, can i use H? I am using the first benchmark of SSR (1977) as base for the turbogenerator model.Again, thank you for your great explanation.
@@ashishpurohit9138 I need to measurement of vibration of a washing where should I place my probes so That I can sense Vibration of all rotating parts in the washing machine
Sir can you please guide me where I can get the derivation of this method (book name please) and if ur video is there kindly give me information about it also . Thank you sir it is very helpful.
@@ashishpurohit9138 thanks for the reply.. I have used the same equation as you have mentioned with A00 and A11 as a 4*4 null and identity matrix and m, k, c with its usual meanings with size 4*4..
Sir, It's a very nice lecture, but iam facing problem in calculating frequency response of beam with harmonic loading. I want to know how to plot frequency response curve in matlab.
@@ashishpurohit9138 yes, I am now trying to write a Matlab code for 2dof undamped system to predict critical natural frequency that may in it flutter will occur in wings Your video was beneficial to help me finishing the Matlab code I intend to expand my analysis by using FEM
Hi, Actually for vibration there are a number of books (S S Rao, Mechanical Vibration) ( Schaum's Outline of Mechanical Vibrations) etc. however for MATLAB, I do not use a book as such, My area of interest is vibration and I do coding for UA-cam videos/personal interest or for my academic work, these videos are developed using theory from std books and code is developed by myself.
@@ashishpurohit9138 thanks for your reply,is it also the same case if it's a complex number and the real part positive? i meant it's an undamped system

Such a nice presentation. Definitely you have achieved great skills. Thank you from an IIT research scholar.

Great explanation bunch of thanks ,amazing man
Nice videos ......
Tell us more on how can we decide the points of where to measure vibrating using eigen vector and eigen values
Thank you for watching, can you please elaborate the query

Nice work. Respect!
thank you sir. Pls make a nonlinear spring/damper system also. very helpful
Thankyou Sir.
It was amazing!!
hi dear.... how can get the same out put but with 4DOF?
Sir can you please guide me where I can get the derivation of this method (book name please) and if ur video is there kindly give me information about it also .
Thank you sir it is very helpful.
You can read any book where multi degree of freedom vibration is given. But actual concept of eigen value will be in mathematics book
Sir, is solution of a damped system same as the solution of a quadratic eigenvalue problem?
At 15:19 aren’t beta 1 and beta 2 the damped natural frequencies instead of the undamped natural frequencies?
what will be the A matrix for 4 dof system in damped vibrations?
At 13.53 sec matrix A is given, that is valid for any dof. Just put M C and K matrix with a zero matrix.

Sir can i contact with you .i really impress with your teaching style.must reply sir

Sir, It's a very nice lecture, but iam facing problem in calculating frequency response of beam with harmonic loading. I want to know how to plot frequency response curve in matlab.
You have to apply fft command, see my previous video of fourier transform
Sir....quantum physics kaise kre
can you please make a video about aeroelasticity problems and coding in Matlab. if you do that's will be great
Are you interested in predicting flutter
@@ashishpurohit9138 yes, I am now trying to write a Matlab code for 2dof undamped system to predict critical natural frequency that may in it flutter will occur in wings
Your video was beneficial to help me finishing the Matlab code
I intend to expand my analysis by using FEM
CC=[A00 A11; -inv(M)*K -inv(M)*C]; [v3 fr3]=eig(CC) Do you have a reference book for this formulas?
May I ask which books are you using?

@@ashishpurohit9138 Thank you!!
what if we have zero real value in the damped eigenvalue?
Real part indicates damping..if it is zero means we are dealing with an undamped system
@@ashishpurohit9138 thanks for your reply,is it also the same case if it's a complex number and the real part positive? i meant it's an undamped system
please speak clearly
