Abstract
Изобретение относитс к области метрологии и может быть использовано дл оценки трибологических свойств материалов в виде пасты. Цель изобретени - повышение точности путем учета силы трени пасты о поверхность обоймы, в которой паста размещаетс , и силы трени пустой обоймы о поверхность контробразца. Коэффициент трени рассчитывают по формуле f((), где F - сила трени образца в обойме по поверхности контробразца; F - сила трени пустой обоймы под нагрузкой Я| по той же поверхности образца; Р - нормальна нагрузка на образец; Р - сила, необходима дл ст гивани обоймы с образца. 1 ил. ND 4 СЛ со сл The invention relates to the field of metrology and can be used to evaluate the tribological properties of materials in the form of a paste. The purpose of the invention is to improve the accuracy by taking into account the strength of the friction of the paste on the surface of the holder, in which the paste is placed, and the strength of the friction of the empty holder on the surface of the counter piece. The coefficient of friction is calculated using the formula f ((), where F is the force of friction of the sample in the holder on the surface of the counter piece; F is the force of friction of the empty holder under load I | along the same surface of the sample; P is the normal load on the sample; P is the force needed to tighten the cage from the sample. 1 ill.
