I need a matlab code to find the natural frequencies of an Indian Railway coach. However, please provide additional info if any to caclculate atleast one fundamental frequency?
I have determined the natural frequencies of 37 DOF rail vehicle system (formulated using Lagrangian method) in MATLAB. I am attaching MATLAB program you required
Thank You Sir. Could you let me know how the frequencies are calculated in Hz. Because the statespace method which is used gives some value like for 1st mode 0.000 + xxxx i. Let me know how you calculate the frequency in Hz from the xxxx value.
