1、座椅舒适度研究基于温度的炖椅舒适度客观评价方法研究刘卓夫1,李恩会1,李峻夫1,CascioliVincenzo2,IleuschIAndrew3,McCarthyWPeter3(1哈尔滨理工大学测控技术与通信工程学院测控技术及仪器黑龙江省高校重点实验室,哈尔滨,中国,150080;2MurdochUniversityChiropracticClinic,Murdoch,WesternAustralia,6150;3WTOC,UniversityofGlamorgan,Pontypridd,United
2、Kingdom,CF371DL)摘要建立了人体-座椅接触面的温度模型,利用实测温度数据验证了模型的精度。从座椅温度特性曲线中提取出了三个评价指标:擁椅表面最终温度,朋椅衣血温度的最人变化率以及座椅表面的平均温度。建立了基于评价指标的座椅舒适度客观评价体系。利用评价体系对三种材料座椅(泡沫、压模和木质座椅)的计算表明:泡沫座椅的舒适度得分为8.82,压模座椅的舒适度得分为5.85,木质座椅的舒适度得分为4.49。通过主观测评法得到的座椅舒适度得分情况为:泡沫座椅的舒适度得分为&36,压模朋椅的舒适度得分为
3、7.27,木质朋椅的舒适度得分为5.36o可见,基于廉椅表面温度的座椅舒适度客观评价体系具有一定的实用性。关键字温度模型;座椅舒适度;评价指标1,JunfuLi1,CascioliVincenzo2、HouschThehighereducationalkeylaboratoryforInstrumentationsofIleilongjiangProvince,(1andObjectiveevaluationofsittingcomfortbasedonbody-seatinterfacetempera
