AbstractA design procedure for nonstationary production systems is outlined. On the basis of the generalized mathematical model, specific models for components of nonstationary systems are developed. In particular, a model for slipway finishing of a part prior to welding in submarine hulls is proposed.

AbstractModels based on regression analysis for predicting the operational efficiency of high-pressure roller crushers are considered. A systematized and structured production database is created and statistically analyzed. The consistency of the data is verified. The parameters with the greatest influence on the productivity are identified. The ba...

AbstractThe thermal influence of the tooth geometry in a conical gear is considered for the case of milling by a cutting head. Formulas are derived for the maximum temperature and the temperature field in cutting as a function of the geometric parameters of the tooth. On that basis, research in a virtual environment corresponding to the actual cond...

AbstractFriction stir welding of butt joints in aluminum alloys is considered. Experiments show that, with disruption of the welding temperature and time, defects localized at the boundary of the weld seam are observed: specifically, gaps due to the differential deformation of the seam and the matrix.

AbstractFor surface texture with microprojections bounded by concave semicircles in two-dimensional space, analytical formulas are derived for the probability of filling of the surface layer with material, both within cross sections and layers and over the volume as a whole. Comparison of probability estimates obtained by graphical and analytical m...

AbstractFor surface texture with microprojections bounded by a mixture of concave and convex semicircles in two-dimensional space, analytical formulas are derived for the filling probability of the surface layer, both within cross sections and over the volume as a whole. Comparison of probability estimates obtained by graphical and analytical metho...
