ABSTRACT
Despite the extensive use of Frequency Based Substructuring (FBS) in vehicle dynamics and NVH (Noise, Vibration, and Harshness) analysis, challenges remain in predicting vibrational responses due to complex boundary conditions and limitations in experimental modal analysis. Traditional methods like finite element analysis (FEA) and multibody dynamic simulation (MBD) are time-consuming and require extensive material data, highlighting the need for more efficient and structured modeling approaches. This paper introduces a hybrid FBS-based modeling approach that integrates experimental and numerical data with measurements from disassembled subsystems, enhancing the prediction of noise and vibrations from tire contact excitations. Due to the importance of partitioning in the FBS method, two partitioning schemes are presented: the Minimal Segmentation Approach (MSA), which simplifies the system into the smallest number of subsystems to improve modeling efficiency and accuracy, and the Systematic Element Partitioning (SEP), which breaks the system into smaller, standardized elements to facilitate the creation of a library of subsystems for high-level modeling. Both approaches are applied to a quarter car model, demonstrating improved accuracy in predicting vehicle vibrational responses compared to traditional methods. By using the receptance matrix from disassembled subsystems, this study offers valuable insights into the resonant frequencies of the original dynamic system. Furthermore, due to its modular approach, this method offers flexibility for predicting a vehicle's vibrational performance based on different subsystem modules available in the design shelf by car manufacturers for the early development phase, where building a full vehicle FEM is challenging.
