Question #1: Derive the governing equations for the vehicle model depicted below. By using the data given, find the natural frequencies and corresponding mode shapes. Question #2: If this vehicle is cruising at a speed of 20 km/h speed on a level road with harmonic profile, calculate the displacement response amplitudes that will be observed at COG. Assume that the road profile has a 0.01 m amplitude and 10 m wavelength. Repeat the same analysis for the vehicle speed of 40 km/h. kar kar LET Wyw Yrw My ker ya D: Vehicle Data Sprung mass: my = 720 kg Mass moment of inertia of sprung mass: 1) = 640 kgm2 Unsprung mass (Front and Rear): m; = m, = 40 kg Stiffness coefficient of suspension (Front and Rear): ksf = ks = 21000 N/m Damping coefficient of suspension (Front and Rear): Csf = Csr = 500 Ns/m Stiffness coefficient of tire (Front and Rear): kus = ker = 105035 N/m Distance between front axle and Cog: b2 = 1.5 m Distance between rear axle and COG: b1 = 1.1 m
