Week 4 Challenge 1- Vehicle frequency target estimation

1) Kr = Ms*(2pi*fs)^2 - find ride rate(Kr)

2) Kw = (Kr*Kt)/(Kt-Kr) - find wheel rate(Kw)

3) MR = d1/d2*cos(90-a) - find Motion ratio(MR). Here 'a' is made with horizontal.

4) Ks = Kw/MR^2 - find the spring rate(Ks)

5) t = Wheelbase/Vel. - Find time lag(t)

6) fs.rear = 1/((1/fs)-t) - Find sprung mass frequency at the rear.

7) Find Kr.rear, Kw.rear, MR.rear and Ks.rear with the same above equations.

8) fus = 1/(2*pi))*(Kr.rear/Mus)^0.5 - Find the unsprung mass frequency at the front. The find fus.rear at the rear using the same eqn.

9) Frequency Ratio = fs.rear/fs - Find the frequency equation

10) Plot graph between time and e^(-t)*sin(wt) to obtain front and rear bump oscillation.
