高速运动条件下玄武岩摩擦系数的实验研究

Experimental Study of Friction Coefficient of Basalt under High-speed Movement

摘要: 在MM－1000型摩擦磨损试验机上采用不同试验条件对玄武岩试件进行了高速摩擦试验研究，结果表明：摩擦表面载荷、运动速度以及摩擦速度以及摩擦表面特性等因素均对摩擦系数产生影响；摩擦系数随载荷的增大呈现减小趋势；对于饱和吸水试件，摩擦系数随运动速度增大持续降低；在其它试验条件下，饱和吸水试件的动摩擦系数比干燥试件明显要低。

Abstract: The friction coefficient of basalt against basalt under high speed sliding was examined on an MM 1000 test rig. The variation of the friction coefficients with the load applied, the sliding speed, and the friction surface properties was investigated. As the results, the changing tendency of the friction coefficients is dependent on the load, sliding velocity and surface characteristics of the frictional pair.With increasing of the sliding velocity the friction continuously drops down.The friction coefficients of the saturated samples are lower than those of the dried ones.
