Abstract
This paper presents the application of a modal parameter estimation technique, namely the Linear Identification by Polynomial Expansion in the Z-domain (LIPEZ) method, to automotive carbon fibre components. In particular, a leaf spring was chosen for its simple geometry and a door panel of an electric vehicle for its high influence in global NVH characteristics of vehicles. Both elements were experimentally tested with free-free boundary conditions under a random input force; the same test is reproduced at simulation level in order to perform a results correlation.
