Research on Vehicle Tire Noise Prediction Method Based on Transfer Learning
摘要
To address issues in traditional tire noise prediction methods such as simplified assumptions in physical modeling, insufficient generalization ability of data-driven models with small samples, and lack of multi-band noise collaborative analysis, this study proposes a multimodal tire noise prediction method that integrates transfer learning with physical mechanisms. By constructing a transfer learning network to extract geometric topological features of the tread pattern combined with a channel attention mechanism for dynamic weighting, an innovative physically-constrained hybrid loss function and multi-objective regression architecture are designed. Based on 126 sets of semi-anechoic chamber experimental data, a grouped cross-validation strategy is used to validate model performance. The results show that the combination of ResNet101 and LightGBM achieves the best performance in cross-modal feature fusion, with an average absolute prediction error of 0.66 dB, a coefficient of determination R2 of 0.97, and 96.96% of samples having prediction errors below 2 dB. The physical fundamental frequency constraint reduces model error by 15%, effectively balancing the advantages of data-driven and mechanistic models.
