打開(kāi)文本圖片集

摘 要：以軌道車輛常用的氯丁膠、聚氨酯膠、彈性體膠和丙烯酸膠4類共12款膠粘劑為研究對(duì)象，建立了膠粘劑綜合氣味指數(shù)評(píng)價(jià)體系，并與主觀愉悅度評(píng)價(jià)結(jié)果進(jìn)行了匹配性分析。研究表明，綜合氣味指數(shù)評(píng)價(jià)結(jié)果不僅與愉悅度評(píng)價(jià)結(jié)果有很好的一致性，且能判別主觀愉悅度維度無(wú)法區(qū)分的膠粘劑氣味大小，有實(shí)際應(yīng)用價(jià)值。

關(guān)鍵詞：軌道車輛；膠粘劑；愉悅度；閾稀釋倍數(shù)；綜合氣味指數(shù)

Abstract：Taking 12 kinds of adhesives commonly used in railway vehicle as the research object，including neoprene，polyurethane，elastomer and acrylic adhesive，the evaluation system of adhesive composite odor index was established，and the matching analysis was carried out with the evaluation results of subjective pleasure dimension.The results show that the comprehensive odor index evaluation results not only have good consistency with the pleasure evaluation results，but also can distinguish the odor size of adhesives that cannot be distinguished by subjective pleasure dimension，and have good practical application value.

Key words：railway vehicle;adhesive;hedonic tone;dilution multiple;composite odor index

目前，軌道交通行業(yè)膠粘劑氣味評(píng)價(jià)主要參考汽車標(biāo)準(zhǔn)VDA 270，分6個(gè)層級(jí)對(duì)膠粘劑固化物進(jìn)行主觀氣味強(qiáng)度評(píng)判，簡(jiǎn)單快捷，但有時(shí)無(wú)法準(zhǔn)確評(píng)判高低，且未將人的心理感受程度考慮進(jìn)來(lái)。（剩余3200字）
