摘要
文章以变速器敲击为研究对象,在文献~([1])基础上提出了基于支持向量机回归的变速器敲击声品质非线性评价方法。文章首先研究了支持向量机回归原理,对文献~([1])中的试验结果进行归一化处理,以归一化后的客观评价结果作为模型输入,归一化后的主观评价结果为输出,引入支持向量机回归方法建立了变速器齿轮敲击声品质非线性评价模型,并对模型进行优化与检验。
This paper takes transmission rattle as the research object, On the basis of literature~([1]), puts forward the sound quality evaluation method of transmission rattle based on Support Vector Machine, The test results in~([1]) are normalized, the objective evaluation results after normalization are used as input of the model, and the subjective evaluation results after normalization are used as output. The Support Vector Machine regression method is introduced to establish the non-linear evaluation model of transmission gear rattle quality, and the model is optimized and tested.
