滑动摩擦系数的物理意义剖析

摩擦系数的测定和分析对当今节能和节材的方针具有重要意义。文章指出,由于古典摩擦定律存在着一定的局限性和不确切性,因而对摩擦系数物理意义进行重新分析很有必要。本文通过一系列金属材料的摩擦试验所测得的摩擦系数值及其变化规律,提出了对摩擦系数物理意义的补充,认为尽快地制订摩擦系数测定标准和建立摩擦系数数据库来代替追求统一数学计算的模型是切合实际的,并指出了摩擦系数只有靠实测来确定的方向。

An Analysis of Coefficient of Sliding Friction and Its Physical Interpretation

Nowadays, the determining of the coefficient of friction is of great significance to the policy of energy and material saving. Due to the limitations and ambiquity of the old frictional law, this paper points out the necessity of analysing the physical interpretation of coefficient of friction. From the data of coefficient of friction and its variable law obtained through a series of tests made on metal, a supplement to the physical interpretation of the friction coefficient is suggested. It is also considered practical to Set up a measuring standard and data bank for determining the friction coefficient instead of finding a unified mathematical model as it is only through testing and measuring could the friction coefficient be obtained.
