In this paper, a Frequency Response Function (FRF) measurement based ALCO (Anisotropic Lining elastic Constants Optimization) method is introduced. ALCO is an extension of one popular dynamic response based measurement method - the Resonant Ultrasound Spectroscopy (RUS) method. The ALCO method provides a practical alternative to the ultrasonic measurement (e.g. ETEK) for acquiring friction material elastic constants, especially for NAO (Non-Asbestos, Organic) materials. The method requires verifications of pad assembly modal information (frequencies and mode shapes) of all modes between FEA and measurement, under same load condition (free-free). Therefore, it ensures a well correlated NVH simulation model, at least at the component level.
