Model-based analysis of construction design of technological adapter for magnetic-pulse processing of plants in horticulture

The article analyzes the features of design of an adapter unit for magnetic-pulse processing (MPP) of plants. It is necessary for radiation of plants by a low frequency 0-100 Hz magnetic field with simultaneous additional synchronous exposure to light with 445-650 nm waves. Classification of the agricultural technological adapters is presented. Analysis of it showed that the electrocylinders with electronic control elements placed on a frame are suitable for construction of a technological adapter of MPP of plants better. In a software environment of Solid Works/Simulation by means of the module of physical simulation the authors visualized the kinematic 3D model of the technological adapter and create a mesh Finite Element Analysis. The studied model placed at fixing three-point hinged system. Load of 50 N was applied to the guideway in the place of fastening of the working elements MPP over the entire surface. The dynamic characteristics of technological adapter MPP, frequency analysis, analysis of stress-strain state of the structure and its components were estimated. The resonance frequencies values were obtained. Zones of concentration of tension 50 mm apart the upper point of fixing of the actuator to a guideway were determinated. Their maximum values reach 40 MPas. Features of distribution of tension dispersion of in these zones are revealed, spectrum of the equivalent tension of model are received. The resonance frequencies equal 0.2-9.2 I rad/s at different modes of vibration of the technological adapter. Resistance to impact of sinusoidal vibration is revealed. The found resonance frequencies are outside the range of the frequencies influencing the technological adapter in case of its operation and transportation. The modelling uncertainty is not more than 5 percent. In case of loading of the technological adapter with MPP working elements (magnetic inductors) of 50 N vertical offset of a guideway makes 1.16 mm. The developed technological adapter of manipulyatorny type, with the simplified construction and the reduced metal consumption, allows to automate completely magnetic-pulse processing of plants with a possibility of automatic adjustment to different agrotechnological parameters of plantings. Frequency of impulse and luminous radiation and time of exposure is showed on control box of the electronic device. Use of special technical means for impulse magnetic processing of garden cultures improves a rooting ability of cherry cuttings by 1.8 times, black chokeberry - by 1,4, blackberry and raspberry - by 1.5-2.0, honeysuckles - by 1.4 times in comparison with the untreated cuttings. The quantity of roots at the same time increases by 21-48 percent, length - for 25-61 percent. Application of MPP when growing of the implanted cuttings in the greenhouse increases survival obyf blackberry by 10 percent, honeysuckles - on 18, mountain ashes - by30 percent. The amount of cuttings growth increases by 14-46 percent.
