Горик, Олексій ВолодимировичКовальчук, Станіслав БогдановичБрикун, Олександр МиколайовичЧерняк, Роман Євгенович2020-12-222020-12-222020-09https://dspace.pdau.edu.ua/handle/123456789/9014The results of experimental studies of a separate contact dynamic interaction of a spherical non-deformable pellet with a plastic flat metal surface at different angles of attack ( 20° ≤ α ≤ 90° ) at high speeds ( v ≈100 m/s ) are presented. A method is described for determining the nature of the viscoelastic resistance of a surface layer attacked by a pellet during contact displacement along the normal to the surface and rigid plastic resistance during tangential displacement, which can be used to establish the processing regimes of products by a mass flow of abrasive particles, in particular, shot-blasting cleaning. The results of comparing the obtained and known theoretical data with each other and with experimental studies are presented.attacking pelletsurface layer deformationviscoelastic resistancetrace parametersspeed and angle of attackdynamic hardnessатакуюча дробинкадеформування поверхневого шарув'язкопластичний опірпараметри слідушвидкістькут атакиатакующая дробинкадеформирование поверхностного слоявязкопластическое сопротивлениепараметры следаскоростьугол атакиArticlehttps://doi.org/10.4028/www.scientific.net/KEM.864.217
