摘　　要：特网网布作为高端办公椅的接触面材料,因其良好的弹性和透气性,备受消费者青睐。但有关特网材料的力学性能对办公椅舒适度影响的研究报道较少,严重制约了网布办公椅的研发升级。研究了特网的拉伸力学性能和座面绷紧度对不同体型人群的臀腿部体压分布和主观舒适度的影响。首先,测试分析了两种特网材料经、纬方向的拉伸力学性能;其次,通过改变特网尺寸量化了3种特网座面的绷紧度,并测试分析了6种特网座面与3种不同体型人群之间的体压分布;最后,针对6种不同特网和绷紧度的座面进行了舒适度主观评价。结果表明:特网种类和绷紧度对人体臀腿部的峰值压力、最大压力梯度和平均压力梯度有显著的交互作用。当座面为MW特网、绷紧度为T时,峰值压力、最大压力梯度和平均压力梯度最低;当座面为MJW特网、绷紧度为T时,峰值压力、最大压力梯度和平均压力梯度最高;综合主观评分和体压指标得出MW⁃T座椅的舒适度最高。本研究从主客观两方面分析了不同特网种类和绷紧度对座面舒适度的影响,为网布办公椅的网布座面设计和舒适度提升提供了科学依据。Mesh fabric,as the contact surface material for the high⁃end office chairs,has gained significant popularity among consumers due to its excellent elasticity,breathability,lightweight,and esthetic.However,limited studies have investigated the effects of mechanical performance of mesh fabrics on sitting comfort,which seriously restricted the development of mesh office chairs.Therefore,it is necessary to carry out relevant research to explore the relationship between the mechanical performance of mesh fabrics and the sitting comfort of mesh fabric office chairs,which can lay a foundation for future development in this field and help the office chair manufactures to develop new products.This study investigated the effects of the tensile properties of mesh fabric materials and seat foundation tautness on the sitting pressure distribution and the sitterssubjective comfort evaluations.Firstly,the tensile properties of two types of mesh fabric materials were tested and analyzed.Secondly,the sitting pressure distribution of 18 participants with different body mass indexes sat on six mesh office chairs with two types of mesh fabric materials and three types of seat foundation tautness were investigated.At the end,the subjective evaluations of sitting comfort were conducted for the six mesh office chairs.Results indicated that the mesh fabric type and seat foundation tautness had significant interaction effects on the peak pressure,maximum pressure gradient,and average pressure gradient of human buttock⁃leg region.The peak pressure,maximum pressure gradient,and average pressure gradient were the lowest when the seat surface was MW mesh fabric and the tautness was T.The peak pressure,maximum pressure gradient,and average pressure gradient were the highest when the seating surface was MJW mesh fabric,and the tautness was T.In addition,both of subjective ratings and sitting distribution results indicated that the highest level of sitting comfort occurred during the MW⁃T seat was used.Overall,this study reported the effec
