摘要
测量不同法向荷载作用下橡胶与岩石间的最大静摩擦系数,分析了不同法向荷载作用下橡胶的摩擦机理。使用厚度为3 mm和5 mm的橡胶为试验材料,法向荷载分别设置7.71 KN、14.835 KN、21.99 KN、29.115 KN和36.27 KN,试验结果表明:随着法向荷载的增大,橡胶与岩石间的最大静摩擦系数均呈现先快速减小后缓慢减小的趋势。
The maximum static friction coefficient between rubber and rock under different normal loads was measured, and the friction mechanism of rubber under different normal loads was analyzed. Rubbers with a thickness of 3 mm and 5 mm were used as test materials. The normal loads were set to 7.71 KN, 14.835 KN, 21.99 KN, 29.115 KN, and 36.27 KN. The test results show that with the increase of normal load, rubber and rock The maximum static friction coefficient among them all showed a trend of rapid decrease and then slow decrease.
