摘　　要：为建立一款牵引电机空载条件下的声品质预测模型,首先开展了电机空载时多个转速下不同位置处的噪声测试,获得了响度、尖锐度、粗糙度和抖动度等声品质客观参数,并分析了各声品质客观参数随转速的变化规律;然后采用等级评分法对40个声样本开展了主观评价,采用箱线图剔除异常数据,获得各个声样本主观评价平均分;最后分别采用多元线性回归法和代理模型法建立了电机声品质预测模型。后者相比前者预测精度更高,该方法和研究结果可以为后续电机声品质优化工作提供参考。To establish a sound quality prediction model for traction motors under no-load conditions,noise tests were conducted at different positions at multiple rotational speeds.Objective parameters of sound quality,such as loudness,sharpness,roughness,and fluctuation strength,were obtained,and the variation patterns of each objective parameter with rotational speed were analyzed;Jury test was conducted on 40 sound samples using a rating system,and abnormal data was removed using a box plot to obtain the average subjective evaluation for each sound sample;Finally,multiple linear regression and surrogate model methods were used to establish motor sound quality prediction models.The latter has higher prediction accuracy compared to the former.This method and research results can provide reference for subsequent optimization of motor sound quality.
