Gumeniuk I. Substantiation of the parameters and the vibrational modes shank cultivator for loosening the soil.

The dissertation is devoted to reducing of energy process of tillage by research of parameters and modes of vibration tillage tools. The main attention was paid to identify the relations of amplitude-frequency characteristics tillage tools with physical and mechanical properties of soil. Based on analysis of existing tools, theoretical and experimental studies the author have determined the structural scheme and set reasonable values of parameters and modes of vibration tillage tools which allows for 12-16% lower value of traction resistance. According to the research an experimental model of vibration tool with elastic suspension was designed and manufactured, which further proved its efficiency and effectiveness.
