Optimization of dynamic characteristics of the hydraulic drive system of the cultivator

Abstract

Enhancement of technological processes’ efficiency in agriculture can be achieved through the optimization of technological, structural, and performance characteristics of agricultural machinery. Modern machinery should have high productivity rate, ease of operation, high level of standardization and minimal expenditures of energy resources. The paper gives examples of the implementation of flow-dividing valves for the maintenance of the requested level of synchronization in the hydraulic drive of the agricultural equipment using the example of folding cultivator. The improved calculation hydraulic model of the cultivator and scheme of throttling flow-driving valve of non-spool type with plunger setting device are presented. The article gives the numerical scheme of the hydromechanical drive system of the cultivator which gives consideration to the volume coefficient of stiffness. It contributes to the exact accuracy of calculations and analysis.
