两种坐姿下身体压力分布与坐姿舒适度研究

Study on Body Pressure Distribution and Sitting Comfort in Two Seated Positions

探究两种坐姿下的身体压力与坐姿舒适度之间的相关性。利用人体压力分布测量系统,获得最大压力、平均压强、平均压力以及接触压力和最大压力梯度等人体压力分布量化指标,采用主观评价与客观测试相结合的方法,分析人处于直立坐姿和斜倚坐姿状态,身体出现不适部位(腿部、臀部、腰部)与坐姿舒适性的关系。坐姿舒适性和人体出现不适部位的相关性显著,而且人体压力分布结果与主观评价结果良好吻合。坐姿舒适度与压力分布间存在相关性关系将对基于人体工程学领域下的座椅的设计具有指导性意义。

The Objective is to explore the correlation between body pressure and sitting comfort in two sitting positions.The Methods is using the human body pressure distribution measurement system,quantitative indexes of human body pressure distribution such as maximum pressure,average pressure,average pressure,contact pressure,and maximum pressure gradient were obtained.A combination of subjective evaluation and objective testing was used to analyze people in an upright sitting position and reclining.Sitting position,the relationship between discomfort in the body(legs,hips,waist)and sitting comfort.Results is a significant correlation between sitting comfort and uncomfortable parts of the human body,and the results of human pressure distribution were in good agreement with the subjective evaluation results.Conclusion is the correlation between sitting comfort and pressure distribution will be instructive for seat design based on ergonomics.
