摘　　要：实验研究了4种聚氨酯材料的粘着及摩擦性能,目的是选择合适的材料来制造特种机器人的足掌,其设计以壁虎脚为仿生对象。结果表明,负法向力(即粘着力)随法向力的增加而呈对数规律增加;在负法向力下,切向力随负法向力的增加而线性增加;在一定负法向力下,切向力随初始法向力的增加按对数规律增加。For the special robot's foot design based on imitating the gecko's foot, the characteristics of adhesion and friction of 4 samples of polyurethane were tested. The experimental results show that the adhesion increases with the magnitude of normal load at the logarithmic rule; that tangential force increases with magnitude of normal load at the logarithmic rule; and that tangential force increases with magnitude of negative normal load at the linear rule.
