수치적 방법에 의한 차량현가장치의 기구학적 민감도해석

A numerical approach for performing kinematic design sensitivity analysis of vehicle suspension systems is presented. Compared to conventional analytic methods which requires explicit derivation of sensitivity equations, the proposed numerical method can be applied with any kinematic analysis method. An algorithm based on Lagrange polynomial is developed to ensure efficiency and accuracy associated with numerical differentiation. Through a kinematic design problem that determine the optimal suspension configuration that satisfies multi design criteria, the validity and usefulness of the approach is demonstrated.
