| Abstract (English): |
To investigate the effect of desk and chair height configuration on human sedentary fatigue, in this paper, experiments were conducted in a simulated sedentary office environment. Using a combination of subjective and objective analysis methods, the Tactilus real-time pressure distribution measurement system was used to collect dynamic body pressure distribution signals for the entire 2-hour sitting office process under 9 parameter configurations. The subjective evaluation results obtained by the free modulus amplitude estimation method were combined to evaluate and analyze the situation of prolonged sitting fatigue. The results indicated that fatigue in sedentary individuals was mainly concentrated in the shoulders, neck, waist, and upper back of the upper body, and the fatigue sensitivity and relief speed of different body parts varied a lot. The distribution value of seat surface pressure tended to increase gradually as the subject finds a comfortable sitting position. In the height design of tables and chairs, the difference in height is crucial. When the difference in height was taken as 1/3 of the sitting height and the sitting height was taken as 6 cm below the calf height, the degree of human fatigue was minimized. Properly reducing the height of the chair can relax the legs. In order to reduce fatigue, the sitting position should be interrupted within 30~60 min. [ABSTRACT FROM AUTHOR] |

为探究桌椅高度对人体久坐疲劳的影响, 本文模拟久坐办公环境进行试验。采用主客观相结合的人体疲劳分析方 法, 利用Tactilus实时压力分布测量系统, 对9组参数配置下的2 h坐姿办公全程动态体压分布信号以及自由模量幅度估计法 获得的主观评价结果, 进行久坐疲劳评估与分析。结果表明：人体久坐疲劳主要集中于上半身肩颈部、腰部以及上背部, 且不同身体部位疲劳敏感度和缓解速度不同。当受试者找到舒适坐姿后, 座面体压分布值增长趋向平缓。在桌椅高度设 计中, 差尺是关键。当差尺取坐高的1/3, 座高取小腿加足高下6 cm时, 人体疲劳程度最小, 且适当降低椅高可放松腿部。 坐姿达到30~60 min时, 为减少疲劳可打断坐姿状态.
