Fa V = FI = The differential equation representing vehicle traction power is given by -1 pcpA (r1v3 + r2v – r3) where ri = + fiWcoso 2 Mv r2 = w[f. cos 0 + sin 0] Vehicle parameters are given below r3 = ηΡΙ B M = 2500 kg p = 1.218 kg/m3 CD = 0.35 Af = 1.50 m2 f. = 0.0136 fi = 5.184 x 10-7 W e W = Mg g = 9.81 m/s2 Develop MATLAB programs to solve the traction problem: (a) Use ode45 to solve and plot the velocity-time history (up to 150 seconds) for power Pr = 60, 80, 100 and 120 kW and grade = 4 %. (6) Use ode45 to solve and plot the velocity-time history (up to 150 seconds) for power Pr = 80 kW and grade = 0, 4, 8, and 12%. (c) Develop a SIMULINK model (and a MATLAB program to call the SIMULINK model) to solve for (a) and (b). η = 0.8 7 -5 Note: include xlabel, ylabel, title, legend, and grid on the plots 1
