WebThe roll stifThess, which is the measure of the way in which the springs resist roll, is given by: Roll stiffness = C w x t x 0.08729 N m/deg . for independent suspensions, where C w is the spring rate at the wheel, known as the wheel rate, and t is the track of the car. For beam-axle suspensions: Roll stiffness = Cs x s 2 x 0.08729 N m/deg WebTypical decoupled suspensions employ a bi-directional spring and damper element, which can introduce cost and complexity to develop. Other teams have worked around this by implementing two roll units, one which actuates in either roll direction, but this is a heavier and larger solution.
