随着对人体皮肤摩擦学特性研究的展开,目前还没有适用的设备对脸颊、额头等不规则形状部位进行测试,本文研制了一种便携式的摩擦性能测试仪,并在不损害皮肤情况下进行人体皮肤摩擦性能测试,结果表明:该测试仪使用方便、性能可靠.在0.2~2N的接触正压力和10~60mm/s的滑行速度范围内,皮肤摩擦系数与施加的接触正压力及滑行速度无关.自然状态下,手背、手掌、前臂屈侧、前臂伸侧、前额部位皮肤摩擦系数在性别间的差距较小,但脸颊部位皮肤摩擦系数女性却远大于男性.护肤品处理后,各测试部位皮肤摩擦系数在性别间的差距都有所缩小.
With the development of research on the frictional properties of the human skin,there was still lack of a suitable friction tester to measure the frictional properties of irregular part of human body,such as cheek,forehead etc. A portable frictional property testing apparatus was designated in this paper and measurements on frictional properties of human skin were conducted without hurting the skin. The results showed that the apparatus was easy to use and had good relibility. The friction coefficient didn't folllow general relationship with normal load and sliding speed when normal load ranged from 0.2 to 1.2 N and sliding speed ranged from 10 to 60 mm/s. Friction coefficients of the skins on dorsum manus,palm,forehead,extensor and flexor aspects of forearm didn't show significant difference between male and female in nature status,however,the friction coefficient of cheek of female was much higher than that of male. Differences of friction coefficients of all measured parts between male and female were lower than that after cosmetics treatment.
