The leaf spring is an important component in the suspension system of the vehicle and the parabolic leaf spring is widely applied in the modern vehicles. Accounting for the symmetricity of the structure and loading condition, the leaf spring is simplified to be a planar structure to analyze. Based on the absolute nodal coordinate formulation (ANCF), the computer aided design (CAD) geometric model is transformed directly to the computer aided analysis (CAA) finite element (FE) model. The linear transformation from Bezier triangle to the ANCF triangular element mesh and the general method to construct the curved structure using the ANCF triangular element are proposed. Thus, the integration of CAD and CAA system is facilitated. Using the ANCF element, the complex and time-consuming transformation from the CAD model to the CAA model with the conventional FE is avoided. As a result, the unnecessary error introduced in the intermediate transformation is avoided. The simplified suspension system including a mono-leaf parabolic leaf spring is built and the transient analysis is conducted. The results are compared against those obtained by the commercial FE software ANSYS.
