The analysis of existing technical means for growing plants in controlled conditions of artificial climate is given. The concept of a multi-section climatic chamber is substantiated, design options are proposed, as well as a block diagram of automated control.

In this research work, after allowing the experiment to run, we proved the possibility to dose sand in the sand feeding system with the effect of vibratory displacement. We set the disturbing frequency and amplitude, at which the maximum system performance is achieved. The sand consumption curves were obtained depending on the oscillation frequency, pulse shape, and tilt angle. A model proposed to describe the effect of vibrodisplacement in a sand feeding system. It was established that disturbances cause sand oscillations at multitude frequencies, coinciding with which resonance phenomena occur. In practice, it means the increase in consumption.

In this research, we calculated the key characteristics and parameters of the pneumatic injector using the set input and output gas flow values. We simulated the ejection of excessive air from the ambient to increase the flow rate of the air-and-sand mixture from the outlet chute of the sand feeding system of a locomotive using the CFD package of the FlowSimulation extension of the SolidWorks solid object design environment. We achieved the reduction of the compressed air consumption as compared to the standard locomotive sand-feeding systems.
