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 the research on the tribological properties of human skin, there is no suitable equipment to test irregular shaped parts such as the cheeks and forehead. A portable friction tester is developed in this paper, and it does not damage the skin The test results show that the tester is easy to use and reliable in performance.Under the contact pressure of 0.2 ~ 2N and the gliding speed of 10 ~ 60mm / s, the skin friction coefficient is proportional to the applied contact pressure and gliding speed Regardless of the natural state, the back of the hand, forearm forearm flexion, forearm extensor forehead skin friction coefficient between the gender gap is small, but the cheek skin friction coefficient of women is much larger than the male skin care products after treatment, the test Part of the skin friction coefficient has narrowed the gap between the sexes.
