摘要/Abstract

摘要： 为研究外界压力对粗糙表面摩擦的影响，建立斜面滑块在不同真空度下的模型并进行试验测量在不同真空度下不同摩擦副配伍材料发生初始滑动时的斜面倾角。试验结果表明：随着外界压力增加，滑块发生初始滑动时的倾角增大，静摩擦力也增大。对于硬度小、重量轻以及接触面积大的摩擦副材料和零部件，其所受外界压力的影响更大。当外界压力从真空度-0.095 MPa增加到0 MPa，轴承钢/轴承钢的最大静摩擦力增大11%、轴承钢/聚碳酸酯增大12%，而聚碳酸酯/聚碳酸酯增大39%。由于通常情况下物体间的摩擦性能总是会受到外界压力的影响，因此真实摩擦角应在绝对真空环境下进行测量，而在大气中进行的测量都存在误差。同时可用文中方法测量两物体的实际接触面积。试验表明随着载荷增加实际接触面积增加，跟摩擦学的经验理论一致。

Abstract: The effect of external pressure on friction and contact with rough surfaces of the inclined plane/sliding block under different vacuum degrees is investigated. Angle of the inclined plane at the sliding block of some pairs of materials is measured at different vacuum degrees. The experimental results show that the inclination angle of the inclined plane at the block start sliding and the static friction force increase with the growth of external pressure. The friction pairs with low material hardness, light component and components with large contact area are more affected by external pressure. As the pressure of the environment increases from vacuum degree -0.095 MPa to 0 MPa, the maximum static friction force of bearing steel/bearing steel increases by 11%, polycarbonate/bearing steel goes up by 12%, while polycarbonate/polycarbonate rise by 39%. Often, the block always is subjected by the external pressure, so the friction angle should be conducted in the absolute vacuum environment, then the critical angle of inclined plane is the true friction angle, if conduct in the air will encounter error. It is indicated that, this experimental method can be used to obtain the actual contact area of two bodies. The experimental results show the actual area of contact increases when the load grow up, this is consistent with the experiment and theory of tribology.

Key words: inclined plane/sliding block, external pressure, friction coefficient, vacuum degree
