If I want to simulate 7-dof, I just replace the n=2, to n=7, or any unit I should change from the original code? And what if I want to add the damping coefficient? Can you help me if the system have different masses? Can I get the code?
Latifah, Yes - to simulate a 7-DOF system, just set n=7. The code I developed doesn't include damping (since it was designed for simulating modal responses). If you want to include damping, you can write out your FBD's, and you'll end up with a matrix [B] containing the damping values in your equation(s) of motion. The code in this video relies on the assumption that all the masses are the same value. If you want masses with different values, manually populate the diagonal of the [M] matrix with your mass values, rather than using M = m.*eye(n).
Hello, it's a great work indeed. Could you please do a similar work for torsional vibration and the natural frequencies of a shaft system?
Thank you very much for a video and a MATLAB code. Can you please give a MATLAB code for multi degree of freedom system with damping
Thank you for this video. And could you please give an idea about how to generate this code using the Runge Kutta method
How to add rungekutta fourth-order instead of euler ?

It's great, thank you so much 😇
Sir if I want to use 4 Dof what changes do I have to make in the code ? Please help
If you want a 4-DOF system (ie. four masses), all you have to do is set n = 4 on line 10 of the MATLAB code.
