This section presents the results obtained after processing the provisions using SolidWorks. Schemes of loading of a nut with pressure and the modulus of resistance on a ring are presented, the general kind of a nut with its distribution in two-dimensional finite elements is presented, graphs of correlations between the stresses and strains appearing in a nut shell depending on force acting are established. and undeformed walnut shell and it was presented that the initial crack appears at the junction of the halves of the nut shell.

Today, walnut is one of the niche crops. Only 7% of the land on the planet is suitable for growing nuts, and Ukraine is one of the few countries where the entire territory is suitable for cultivating this crop. According to statistics, in 2019 the area of walnut plantations in Ukraine amounted to 15.8 thousand hectares, of which 85.4% are concentrated in private households and they provide 99.2% of the production of this product. But this factor affects the unstable supply of this crop, as it is difficult to form commodity batches of different varieties of nuts, as well as narrows the range and reduces its cost. The annual consumption of nuts in Europe and the Persian Gulf is 4.2-5.6 kg per person, while in Ukraine the figures are more than modest - only 1.8-2.4 kg, at normal (according to the Institute of Nutrition of the Ukrainian Academy of Sciences ) from 1.5-3.6 kg.

Walnuts are the most popular and beloved. They are not only very tasty, but also very useful. Due to the content of binders, walnut is a good anti-inflammatory agent. Extracts and nut preparations have antitoxic effects, remove various toxins from the body, as they say, cleanse the blood.

The work related to the process of modeling the deformation of the nut shell is very relevant. The obtained results can be integrated into the work of the nutcracker for greater efficiency, which will allow to obtain a better quality product

 

Keywords: modeling, modulus of resistance, splitting, shell, modulus of tension.

History of journal:

In June 1994 the 2nd International Scientific and Technical Conference "Application of vibrations for technological purposes" was organized on the basis of Vinnytsia State Agricultural Institute. Leading experts in this field, noting the significant contribution to the school of Vibration Engineering under the leadership of P. S. Bernyk, proposed to create a professional all-Ukrainian scientific and technical journal "Vibration in engineering and technology..The journal was foundedat Vinnytsia State Agricultural Institute and P.S. Bernyk was elected to be the chief editor .
For all these years (since 1994) theJournal "vibration in engineering and technology" published  119 issues wherestudy of vibration effects, the creation of progressive energy saving technologies and equipment for their implementation were highlighted.
Currently Ihor Kupchuk, Candidate of Technical Sciences, Associate professor, Associate Professor of the Department of Engineering Mechanics and Technological Processes in the Agricultural Industry Faculty of Engineering and Technology Vinnytsia National Agrarian University is the chief editor of the "Vibrations in engineering  and Technology"

The journal "Vibration in Engineering and technology", which has no analogues on the territory of Ukraine, is well known abroad.
