| description | The invention discloses a system for improving the NVH performance of a tractor cab. The system comprises a cab analysis module, a TPA model analysis module and a cab noise determination module. The cab analysis module comprises a data capture module and a vibration sound analysis module, captures the vibration sound of the cab and analyzes the characteristics of the vibration sound of the cab; the TPA model analysis module performs quantitative analysis on the noise level in the tractor cab through finite element analysis and outputs an analysis result; and the cab noise determination module integrates the cab analysis module and the TPA model analysis module to process data, realizes secondary transmission path analysis of the cab by utilizing RNN neural network algorithm self-generation and updating, determines the position and size of cab noise through secondary transmission path analysis, and improves the NVH performance of the tractor cab. According to the invention, the main problem plate and frequency |
