1. A method for providing a suspension system with optimized damper response, wherein a sprung mass is suspended by the suspension system, the suspension system including a wheel assembly having a wheel center and a mass, m, a nonlinear damper wherein the damper is connected between the sprung mass and the wheel assembly, and a spring having a predetermined spring force, F(x), as a function of displacement of the wheel relative to the sprung mass wherein the spring is connected between the sprung mass and the wheel assembly, said method comprising the steps of:

  • providing a substantially constant total force, F(L), on the wheel assembly with respect to the sprung mass during a jounce event over a travel length of the wheel center of the wheel assembly with respect to the sprung mass, wherein the travel length extends between zero and L;

    wherein the wheel center of the wheel assembly has a velocity Uo relative to the sprung mass responsive to the jounce event at the travel length of zero, and wherein the wheel center of the wheel assembly has a velocity of zero responsive to the jounce event at the travel length of L; and

    wherein F(L) is a combination of a damper force, Φ

    (y), provided by the damper and of the spring force, F(x), provided by the spring, where
