Hi all, I have to find the equation using magic formula to model a friction damper to be used in ADAMS software for dynamic simulation.
Y=D*sin[C*arctan{(1-E)*B*X+E*arctan(B*X)}]
I am trying to solve the Magic Formula (tire simulation) for the variables B, C, D and E in the above equation.I have the damper characteristic curve from which I extracted data points. Now I have to fit a curve equation that would fit the behavior it.
If it is possible to fit any other equation (polynomial or trigonometric), would be helpful. Can I fit a spline and extract the equation in this case?
