Abstract

The necessity of intensification of a set of processes in the branches of agriculture and forestry requires the creation of new equipment and innovative technological schemes. There is a crisis in the sphere of constriction of forestry equipment in Russia. Machinery park is decreasing. The import ratio is increasing. In the sphere of grinding the ground cover (leaves) the development of technical solutions is aimed at reducing labor costs from one hand and development of grinding equipment and technologies which promotes reducing energy intensity of grinding process from the other. The theoretical component of leaf grinding by a flexible string, the power balance of the рrocess and the expanded energy optimization by increasing of transverse oscillation energy with optimal rotor speed are considered in the article. We used a set of guitar strings as string-choppers in our experiment. It was taken into account that the manufacturing technology of a string assumes the presence of corresponding vibrations from an external perturbation influence. In our case this effect is provided by the periodic interaction between the string and the material being treated. It bears mentioning that the research statement is the basis for advanced consideration of the ground cover destruction process with the provision of strings resonance oscillations depending on their design parameters and kinematics of the working tool. In the framework of further development it is recommended to use it in forest park and urban roadside areas.
