A car has the following suspension and body parameters Parameter Variable Body mass (kg) m = 870 Vehicle Wheelbase (m) L = 2.34 Vehicle Track (m) t = 1.49 2 Lever Ratio, Front = 1.6 Lever Ratio, Rear λ, = 1.9 COG height (m) h = 0.8 COG distance from front axle (m) C = 1 Roll axis height, front (m) hf = 0.4 Roll axis height, rear (m) hr = 0.7 Roll stiffness, Kroll, measured in Nm/rad, is: kroll kgt² kyt² + 2 2 a) Determine the roll stiffness required to allow the body roll to be 7º when the car is negotiating a corner of radlus 106m at 35m/s. b) If the wheel rate stiffness at the rear is 1.5 times that at the front (i.e. k, = 1.5kt), determine the spring stiffnesses, kt, spring and kr,spring that are necessary to give the required value for kroll.
