Development of Tribometer and Measurement Results of Static Coefficient of Friction Sliding and Coefficient of Rolling Friction by Principle Steep Plane

Abstract

The paper presents a solution of new developed tribometer intended measuring that static coefficient of friction sliding and static coefficient of rolling friction materials of various types. Principles of measurement are theoretically analyzed, presented the basic of structural solutions and some results of measurements. Tribometer is based on the principle of the steep plane and provides a rotation angle of the steep plane with an accuracy of one minute, which provides high precision of measurements. From the point of the possible values of the load contact pairs developed tribometer belongs to a class of micro and nano tribometers.
