Abstract:

With taking into account the rheological properties of farm materials (soil, root and tuber crops, fertilizer, grain, etc.) is modeling the process of impact interaction on them of working bodies of machines. The design formulae of impact deformation and stresses values are derived. As rheological model of material is applied the basic law of linear deformation taking into accounts not only the elastic properties of materials, but also their viscous properties, as well as the propagation velocity of stress and strain. The results of the study would be used at the development of technological processes in agriculture and at calculation of the working bodies of working on the impact principle machines.

Keywords: working body; farm material; impact; rheology.
