Longitudinal stiffness formula
WebThe method makes use of a formula with coeff- fying quantities of the tyre such as slip stiffnesses icients which describe some of the typifying at zero slip and peak values of forces and torques. quantities of a tyre, such as slip stiffnesses at zero This feature would make it possible to investigate slip and force and torque peak values. WebThe Stiffness of spring formula is defined as the extent to which an object resists deformation in response to an applied force and is represented as K = (G*d^4)/ (64*R^3*N) or Stiffness of spring = (Modulus of rigidity*Diameter of spring^4)/ (64*Mean radius^3*Number of coils).
