METHOD OF SETTING FUNCTIONAL CHARACTERISTICS OF AGRICULTURAL MACHINES AND UNITS INTERACTING WITH SOIL AT FIELD TESTS Russian patent published in 2005 - IPC

FIELD: agricultural engineering; testing agricultural machines.

SUBSTANCE: proposed method includes setting, determination and calculation of power (N) required for deformation of solid medium, translational velocity (v) of deforming body and area (S) of deformable medium section. Then, derivative - bulk modulus of pulse of force of resistance to deformation process is determined; volume modulus is dynamic physico-mechanical characteristic of deformation process of solid medium which is calculated by the following relationship: ρ^ν=N/Sν².

EFFECT: low cost of calculations of characteristics of machines and their working members.
