Roll Rate in Race Car Vehicle Dynamics Formulas

Roll Rate or Roll stiffness is the resistance moment generated per unit of roll angle of the sprung mass. And is denoted by K_Φ. Roll Rate is usually measured using the Newton Meter per Radian for Torsion Constant. Note that the value of Roll Rate is always positive.

FAQ

What is the Roll Rate?

Roll Rate or Roll stiffness is the resistance moment generated per unit of roll angle of the sprung mass. Roll Rate is usually measured using the Newton Meter per Radian for Torsion Constant. Note that the value of Roll Rate is always positive.

Can the Roll Rate be negative?

No, the Roll Rate, measured in Torsion Constant cannot be negative.

What unit is used to measure Roll Rate?

Roll Rate is usually measured using the Newton Meter per Radian[Nm/rad] for Torsion Constant. Newton Centimeter per Radian[Nm/rad] are the few other units in which Roll Rate can be measured.
