Longitudinal Nonuniformity

A pair of governing differential equations form the basis for the study of steady-state forced vibration of a sandwich beam with longitudinal nonuniformity in the stiffness and mass of the middle layer. The spatial solution for simply supported boundary conditions is obtained by a Fourier analysis of both material and kinematic variations. The solution is utilized in the numerical study of a sandwich beam with a segmented configuration of elastic and viscoelastic core materials. The results exemplify a tuned configuration of core segments for optimum damping of the first resonant mode.

The article discusses a method for determining the effective parameters of centrifugal concentrators with fluidization of a mineral bed with water through holes in the walls of a rotating cone. The device and the principle of operation of a laboratory setup for studying the constrained movement of mineral particles in a centrifugal field are described. Also, the optimization of the degree of loosening of the mineral bed in the centrifugal concentrator is considered. It was established experimentally that with existing water flow rates the condition of the mineral bed was close to the pressed state. Using the developed method of optimizing the ratio of water pressure in the fluidization system and the separation factor, the optimum water pressure and its flow rate were calculated in laboratory conditions. As a result, it was possible to raise the extraction during the first stage of gravity concentration by 2%. Therefore, it was determined that the degree of loosening depends on the correlation of the separation factor and the water pressure in the fluidization system. Based on the proposed approach, it is possible to develop an automation system to adjust the parameters of the centrifugal concentrators. Based on the results of calculating the balance of the concentration process in the gold extraction plant at the Kedrovskoe deposit, it was established that the application of the proposed methodology helped to improve the efficiency of the centrifugal free-flow concentrator.
