Abstract
A method of optimizing a suspension system to avoid pitch resonance may include determining pitch characteristics of a vehicle for a terrain profile and speed range via a model associated with the vehicle, decoupling front and rear axles by removing pitch inertia from the model, and determining optimized damping for a main damper of a position sensitive damper over a linear range of wheel travel in a bounce control zone based on the pitch characteristics. The method may further include recoupling the front and rear axles by adding the pitch inertia back into the model, and selecting a secondary damper associated with a compression zone or a secondary damper associated with a rebound zone as a selected damper for adjustment based on which of the front and rear axles is limiting. The method may also include performing a damping adjustment to the selected damper and cyclically repeating selecting the secondary damper and performing the damping adjustment until pitch resonance is suppressed.
