The Methodology of the System-Level Topology Optimization for Road Booming Noise 2023-01-0027
Most sub-compact vehicles with the rear multi-link system have road booming noise issues due to bending modes in the rear cross-member. Many engineers in the vehicle industry solve this problem by implementing a dynamic damper on the rear cross-member. However, the additional component of the rear cross-member increases cost and weight. This paper presents the methodology of the system-level optimization for rear cross-member structures to improve road booming noise. A feature extraction methodology is introduced. This method makes possible the application of topology optimization results to real design, rather than the results just being used as a concept suggestion.
