Description

Analytical dependences of the gravitational distribution of granular materials in the horizontal carrier flow acceleration are founded and reasonable parameters of the classifier with variable cross-section of the flow are substantiated. The recommendations for the calculation and use of devices for the extraction of sedimentary minerals are developed. An algorithm for calculating the dewatering process sapropel mechanically with the vibration is developed. The technique of computational experiment is substantiated and the regularities of dynamic processes in heavy-duty friction contact with the roughness and kinematic constraints are stated. An algorithm for the design of rational structures of machine units, algorithm evaluation criteria of error in the results of solving optimization problems related to discrete-continuous interacting systems, are developed. The dependences and the stress-strain state of the shell of the drum lifting machine with a flat traction body are defined. The regularities of stress-strain state of the drum hoisting machine while winding the flat traction body bobbin scheme are analytically stated. The regularities of the influence of the shock-wave loading on the state of the metal surface with examining the relationship between the depth of the doped layer with chemical and thermal treatment and the intensity of pre-shock-wave treatment, are stated.
