摘　　要：为量化人体各部位舒适度对整体舒适性的影响,首先对18个受试者的肩部、背部、腰部、臀部和大腿5个部位施加局部刺激,并根据他们的主观评价,得到了人体各个部位和整体的舒适性水平;接着提出以平均相对得分率为比较依据,运用层次分析法识别出了受刺激5个部位的权重系数;最后通过与另一款座椅试验结果进行对比验证,表明了该试验方案和识别方法的有效性和实用性,为座椅的设计和评价提供了理论依据。In order to quantify the effects of the comforts of different body parts on the overall comfort, asubjective evaluation test is carried out, in which 18 testees are subjected to local excitation on their shoulder,back,waist, hip and thighs respectively, with the comfort levels of both their different parts and whole body obtained. Then a measure of average relative scoring rate of comfort is introduced as the basis of comparison and theweight coefficients of five different body parts subjected to excitation are identified by using analytical hierarchyprocess. Finally another seat is tested as comparative verification, with a result showing that the test scheme and identificationmethod are effective and practical, providing a theoretical basis for seat design and evaluation.
