项目摘要
It is considered that stick-slip phenomenon is determined by the velocity characteristics of the friction, but it has not been clarified in detail, especially, its relation to the properties of the lubricants. The purposes of this research project are; determination of the effect of the lubricant on the stick-slip phenomenon, and analysis of the velocity characteristics of the friction. A ball on disk friction apparatus was made to analyze the effect of the lubricants by obtaining the limiting load where the stick-slip begin to occur. It is found that much attention should be paid to the preparation of the specimen and finishing the surface, because the results may be affected by the slight differences in the surface conditions. It is also found that a polymer compound which was added in the lubricating oil as a viscosity lidex improver may not affect the results by itself alone but it may affects the results when oiliness agent such as fatty acid are present in the lubricating oil.In the next stage of the research work, the friction apparatus was then modified to analyze velocity characteristics of the boundary friction by introducing a personal computer system with A/D converter. It is found that kinetic friction coefficient at the highest velocity of the moving body in the slip process (<mu>_k) decreased with increasing viscosity of the lubricant but it changed to increase beyond certain value of the viscosity. It was also found that slip width was closely related to the <mu>_k value.
一般认为粘滑现象是由摩擦的速度特性决定的,但对粘滑现象的研究还不够深入,特别是粘滑现象与润滑剂性质的关系还不清楚。本研究的目的是:确定润滑剂对粘滑现象的影响,并分析摩擦的速度特性。制作了球盘摩擦装置,通过获得粘滑开始发生的极限载荷来分析润滑剂的作用。结果表明,试样的制备和表面的精加工都可能受到表面条件的微小差异的影响,因此应特别注意试样的制备和表面精加工。还发现,作为粘度脂指数改进剂添加到润滑油中的聚合物化合物本身可能不会影响结果,但当润滑油中存在油性剂如脂肪酸时,它可能会影响结果。对摩擦装置进行了改进,引入了一个个人计算机系统,A/D转换器。结果表明,滑动过程中运动体最高速度处的动摩擦系数(<mu>k)随润滑剂粘度的增大而减小,但当粘度超过一定值时,动摩擦系数又增大。滑移宽度与<mu>_k值密切相关。
