DEVELOPMENT OF MULTI-ATTRIBUTE SIMULATOR FOR INTEGRATED VEHICLE DYNAMICS AND (EXTENDED) COMFORT EVALUATION OF AN ELECTRIC VEHICLE

This paper presents an integrated virtual methodology for assessing electric vehicle dynamics and comfort characteristics up to 100 Hz during development. Electric vehicles face unique challenges: absent powertrain noise exposes secondary vibration paths, while battery packaging and torque delivery require new design solutions, making Vehicle Dynamics and NVH coupling critical. The methodology employs correlated Multi-Body and Finite Element models implemented in a multi-attribute driving simulator featuring high-fidelity motion systems and vibration reproduction across the complete frequency spectrum. This integrated framework enables simultaneous assessment of dynamics and NVH attributes, facilitating early-stage optimization of conflicting handling and comfort requirements. A collaboration with a Hyundai vehicle case study demonstrates the approach's implementation and validation.
