Prediction and Study on the Influence of Propeller Shaft to Vehicle Noise Based on BP Neural Network

摘要

Propeller shaft is one of main sources to arouse vehicle noise. To decrease development cost and shorten development cycle, BP Neural Network model of influence of propeller shaft to vehicle noise was established using MATLAB software, combined with historical data. Then, the model was trained, results showed that it was stable and credible and the error of this model was between -4 and 4, which could be acceptable. Last, noise of the developing vehicle in the company was predicted using the model, offering theoretical reference to related people.
