基于人机工程学的不同床垫材料对人体影响分析

通过受试者仰卧时体压分布对比、纵向压力分布曲线分析、床垫平均压强差异性对比等方法,研究床垫材料对人体仰卧体压分部特性的影响.结果表明:分区弹簧和海绵床垫的最大压力集中在头后部及足跟,整体舒适性较高;记忆海绵垫的最大压力集中在足跟处,乳胶垫压力较均匀,分布在头后部、骶骨和足跟处,但这两者压力值较分区弹簧和海绵垫高,整体舒适性略低;棉胎和棕床垫的最大压力集中在骶骨和头后部,整体接触面积较小,局部不舒适感较强;水床垫与气床垫虽然没有压力过分集中,但整体接触面积较大,人体轮廓模糊不清,长时间使用易疲劳.

Analysis of Effects of Different Mattress Materials on Human Bodies Based on Ergonomics

This paper studies the impact of mattress materials on distribution characteristics of body pressure by comparing subjects＆#39;body pressure distribution when they are supine,analyzing longitudinal pressure distribution curves,and comparing the differences of average mattress pressure.The results show that the subjects are provided with higher overall comfort if the maximum pressure of district spring and sponge mattress is on the back of their head and heels,if the maximum pressure of memory foam mattress is on the heels,and latex mattress pressure is evenly distributed on the back of heads,the sacrum and heel,but their pressure values are higher than district spring and sponge mattress,the subjects feel slightly less comfortable,if the maximum pressure of cotton and palm mattress is on sacrum and back of head,the contact area is small,and therefore some parts of the body feel uncomfortable,although the pressure of water mattress and air mattress is not highly concentrated,the subjects＆#39;bodies are not clear and are more likely to be fatigued if they use such a mattress for a long time,because the contact area is large.
