摘　　要：机械产品的设计已经从功能层面的满足上升到情感层面的满足,功能不再是唯一的重点,机械产品特别是定制产品的性能越来越受到重视。感性意象是用户对产品性能表现形成的印象,决定了产品是否能够满足用户高层次的情感需求。提出一种面向性能的定制产品感性意象评价方法,采集脑电信号用于反映用户的感性意象,并以此为主要依据,验证产品的性能。为了精确、全面地反映用户对于定制产品性能的感性意象评价,综合客观评价法和用户主观评价结果对采集的脑电信号分级标定。以乘客对于高速电梯乘运性能的评价为例,通过小波包分解提取乘客脑电信号的特征,利用随机森林算法实现对于电梯运行过程中脑电信号的分类。从而建立一种针对高速电梯乘运性能的感性意象评价模型,实现脑电数据特征的约简,得到了一种新的电梯乘运性能评价指标。通过脑电信号将乘客使用电梯产品时的愉悦感、舒适性量化表达,为定制产品感性意象评价提供了一个新的理论与方法。The demand for mechanical products design has increased from the functional level to the emotional level.The function of mechanical products is no longer the only focus.The performance of mechanical products,especially customized products,has attracted more and more attention.The perceptual image is the impression of the user on the performance of the product,which determines whether the product can meet the high-level emotional needs of the user.A performance-oriented method for evaluating the perceptual image of customized products is presented.The main basis for verifying the performance of products is real-time acquired physiological signals of customers.To evaluate the physiological signals of customers,the objective evaluation method and subjective evaluation results are employed,which is able to reflect the performance of customized products accurately.This study takes evaluation of high-speed elevator’s ride performance as an example.By wavelet packet transform and random forest algorithm,feature extraction and classification of collected passengers’EEG signals in the elevator’s operation are respectively implemented.A perceptual image evaluation model of high-speed elevator’s ride performance is established and the reduction of EEG data characteristics is realized.According to the proposed method,passengers can express the pleasure or comfort quantitatively,which provides a new perspective for exploring the evaluation method based on the perceptual image.
