Abstract
This article describes the engineering task of wear research, when a part is turned off after a known overhaul service life and its wear is determined. It is examined how the asymmetry coefficient is determined, the modal wear value corresponding to the largest ordinate of the normal wear distribution, etc. The figures presented in the paper illustrate the right-hand and left-hand asymmetry observed during accelerated wear, as well as the typical curve of the wear distribution of machine parts. Scientific-based judgments are presented on whether machine parts have been subjected to accelerated wear. This scientific article is prepared for agricultural specialists, researchers, teachers, postgraduates, undergraduates and students of agricultural universities in the field of training “Agroengineering”.
