Simulation of vibrating process of bulk material
The process of vibrotransporting bulk materials is described. An experimental setup is described. The designs of the developed strain gauges are described. An experimental procedure and experimental diagrams are given. It is concluded that the normal reaction of the layer of the material and the vacuum in the sublayer space depend on the phases of the motion of the vibrated layer of crushed lime, quartz sand and river sand. The simulation of the process of vibrotransporting bulk materials was carried out using the STATISTICA package. An experiment planning matrix is given. It is concluded that there is insufficient experimental data and an extended experimental planning matrix is given. Obtained regression equations describing the process of vibrotransporting crushed lime, quartz sand and river sand. Three-dimensional graphs of the dependence of the rate of vibration transport on the amplitude and frequency of oscillations are constructed for powdery materials with a high content of dust-like particles, for powdery materials with a low content of dusty particles, and for fine-grained materials. The conclusion is made about the most favorable vibration parameters.
