Optimization the start-up mode of bucket elevator by criterion of mean rate of change efforts in traction body during clash on drive drum
(НУБіП України, 2018) Loveykin V.S.; Loveykin J.V.; Tkachuk L.B.
The oscillations of the structural elements, the drive mechanism and the traction body are minimized by optimizing the movement modes of the grain elevator during transient processes, which made it possible to increase its efficiency. Based on the chosen dynamic model, a mathematical model was created using the d'Alamber’s principle. The optimization process of the start-up mode of the bucket elevator was considered by the criterion of mean rate of change efforts in the traction body during clash on the drive drum. Found laws of motion for working branch, the tensioning drum and the drive drum which correspond to the optimal mode of movement of the bucket elevator. Based on the discovered laws of motion were built kinematical characteristics of the main parts of the elevator which are presented in the form of graphical dependencies for the optimal motion mode. The graphical dependencies of the effort changes in the traction body during clash on the drive drum and shrinkage from the tensioning drum also received. Based on the graphical dependencies established that during start-up bucket elevator at the optimal mode of motion there are small oscillating processes that are the smallest just in the optimization by the criterion of mean rate of change efforts in the traction body during clash on the drive drum.

Realization of optimum mode of movement of roller forming installation on acceleration of fourth order
(НУБіП України, 2018) Loveykin V.S.; Pochka K.I.
For the purpose of increase in reliability and durability of roller forming installation the optimum mode of back and forth motion of the forming cart on acceleration of the fourth order is calculated. Kinematic characteristics of the forming cart at the optimum mode of the movement on acceleration of the fourth order are calculated. The design of roller forming installation with the drive from the high-moment step engine which is built in the rolling rollers of the forming cart is offered and provides the optimum mode of back and forth motion of the forming cart on acceleration of the fourth order. Use in installation of the specified driving mechanism leads to improvement of quality of a surface to the processed concrete mix, reduction of dynamic loadings in elements of the driving mechanism, to disappearance of excess destructive loads of a frame design and, respectively, to increase in reliability and durability of installation in general.
