A vehicle suspension dynamic response design sensitivity analysis and optimization technique is presented and illustrated. Dynamic response measures included in the formulation, for use as the abjective function or as constraints, include driver absorbed power, driver peak acceleration, and suspension element travel. Design parameters available to the designer include suspension spring and damper characteristics, suspension dimensions, and parameters in feedback control suspension subsystems. An adjoint variable technique that is generally applicable to such problems is employed and formulas for derivatives of dynamic response measures with respect to design parameters are derived. Numerical results with a five degree-of-freedom vehicle model demonstrate feasibility of the method and may serve as a guide for application to more complex models.
