Research on gear whine evaluation method based on transmission error sensitivity

Abstract

The issue of noise control for electric vehicles has gradually become prominent, and gear whine noise, as a key factor, is crucial for improving the overall performance and quality of vehicles. This paper discusses the transmission error, a key parameter leading to gear whine, and analyzes the influence of load and gear micro modification on the distribution of transmission error, to achieve comparison and optimization of different axle plans. In addition, by statistical analysis of the distribution of manufacturing errors, it is concluded that they accord with a normal distribution. Then, the weighted transmission error is obtained considering error probability distribution, which provides a new approach for evaluating the sensitivity of gear whine noise to manufacturing errors, in order to solve the issue of noise consistency in large-scale production.
