DEM Simulation of Working Speed of Spade Soil Opener Influencing on the Dynamic Behavior of the Soil

Abstract:

To research spade soil opener work performance, based on two-dimensional discrete element method, using the secondary development of CAD technology, by soil opener CAD model to construct a two-dimensional discrete element analysis model soil opener using MFC programming techniques developed two dimensional discrete element simulation system based on building a soil discrete element calculation model of the soil opener process simulation, presented on a computer spade affect the dynamic behavior of the soil, has been the destruction of soil flow deformation achieve spade Soil computer-aided design, provides a new method for the analysis into the performance of the opener, and provide a reference for the design of the cut soil components.
