Дослідження системи перемішування бетонної суміші на імітаційній моделі

Abstract

Based on the mathematical model of the device for the production of concrete mixtures, a simulation model of the device is developed, where the influence of external disturbances on the specified technological process is investigated. A parametric diagram of the concrete mixer has been created and the parameters indicated are included in the mathematical model. The implemented mathematical model takes into account the effects of external and internal perturbations on the process of obtaining concrete mix with specified strength parameters and a given level of solution in the mixer. The level of the solution in the mixer was adjusted by changing the cost of crushed stone, and the strength of concrete, which depends primarily on the concentration of cement in the solution, on the consumption of cement. As a result of experimental and theoretical studies, the transfer function of the control object along the mixture concentration channel is obtained, which will allow developing process control algorithms, as well as the control system as a whole. Acceleration characteristics of the regulatory object in terms of parameters.
