damping factor calculation
damping factor calculation
(OP)
Hello, i'm tryng to calculate the damping factor and damping ratio from some data i gathered. I have plotted the results so i'm trying to use the logarithmic decreament method.
I have measured the amplitudes, so i have Xn and Xn+m, but i keep getting -ve results, and i'm sure thats not right. Surely i should be getting a value lower than 1 as the data clearly shows the system to be under damped.
Any thoughts on where i'm going wrong?
Cheers
