Abstract

The conditions of destruction during processing of compacted soils of agricultural purpose (SAP) at their fast unloading are considered. The stress-strain state of the SAP array after its chipping, shock, shock-vibration or other impulse is considered. The duration, position of the surface and deformation of the SAP rupture, influence on the process of friction and boundary of the zone of destruction of soil are determined. Physical-mechanical and mathematical models that adequately describe the processes of propagation of unloading waves in SAP during their processing / destruction by working bodies of agricultural (soil-cultivating) machines are substantiated. The dynamics of soil destruction during mechanization of earthworks with the destruction of compacted SAP is considered. The process of SAP loading by dynamic efforts is analyzed on the basis of the dependence of the compression intensity of the soil and the size of the deformed zone on the loading rate, pulse duration and physico-mechanical properties of the treated medium / array.
