In the automotive industry, experimental modal analysis is used extensively in new vehicle development to design various components and assemblies for road dynamic loads. Experimentation is essential to bridge the gaps in simulation. In this paper, we present three automotive components exhibiting increasing level of complexity in their dynamic response. These automotive components contain some elements that are difficult to model because of insufficient data available on material properties. The protocol adopted in each case is as follows: 1. Construct a finite element model of the component to deduce modal parameters, namely, natural frequencies, and mode shapes; 2. Experimentally determine the modal parameters of the system under test, including realistic natural frequencies and damping coefficients; 3. Correlate experimental measurement with simulation results. These simulation and experimental studies are carried out with free-free boundary conditions. Data acquisition for experiment, modal parameter estimation, post processing and correlation are performed using an in-house software package.
