The subject of this paper is the solution to specific problems in the measurement of the coefficient of the sliding friction of material pairs using a variable incidence tribometer. The aim of this work was to solve the questions of the measurement of the static coefficient of friction using a variable incidence tribometer from the perspective of metrology. In particular, we intended to research the expression of the credibility of this measurement and the possibility of increasing the credibility of the measurement. Another problem that needs to be solved is the method of carrying out the measurement, which has an impact on its achieved uncertainty. Sliding friction is a phenomenon that depends on many material properties such as contact area roughness, moisture, lubricants, temperature, and relative motion velocity. If environmental conditions are defined, the main input parameter is the relative motion velocity. For this input quantity, friction force becomes a symmetrical problem, and it is only necessary to explore this phenomenon for positive values of velocities. Symmetry in this area simplifies the research of this science topic.

使用可变入射摩擦计测量摩擦系数的具体问题
本文的主题是解决使用可变入射摩擦计测量材料对滑动摩擦系数的具体问题。这项工作的目的是从计量学的角度解决使用可变入射摩擦计测量静摩擦系数的问题。特别是,我们打算研究这种度量的可信度的表达方式以及增加度量可信度的可能性。另一个需要解决的问题是进行测量的方法,这对其实现的不确定度有影响。滑动摩擦是一种取决于许多材料特性的现象,例如接触区域粗糙度、湿度、润滑剂、温度和相对运动速度。如果定义了环境条件,则主要输入参数是相对运动速度。对于这个输入量,摩擦力成为一个对称问题,只需要在速度为正值时探索这种现象。该领域的对称性简化了这一科学课题的研究。
