基于消费者反馈的整车NVH主观评价研究

为了让整车NVH性能主观评价结果更具有对比性,更贴近消费者,重新梳理整车NVH性能主观评价工况和评价项目,利用问卷调查结果计算各工况、各评价项目的权重,并拟合线性回归公式,将每个评价项目的评价结果结合其权重值合成整车NVH性能评价结果。同时利用MATLAB软件搭建NVH主观评价结果计算平台,方便后期结果处理。

Research on Subjective Evaluation of Vehicle NVH Based on Consumer Feedback

In order to make the vehicle NVH performance subjective evaluation results more comparative and closer to consumers,the subjective evaluation conditions and evaluation items of NVH performance of the whole vehicle were reviewed,the results of questionnaire were used to calculate the weights of each condition and each evaluation item.Finally,the linear regression formula was fitted.Combining the evaluation results of each evaluation item with its weight value,the NVH performance evaluation results of the whole vehicle was synthesized.At the same time,MATLAB software was used to build NVH subjective evaluation results calculation platform,convenient for later results processing.
