The Analysis of the Connection of Two Tools of a Modular Device for Soil Application of the Digestate
MetadataShow full item record
The issue of connecting two collaborating tools in the scope of determination of forces occurring in the hitch of the tools was discussed. The analysis was carried out at the example of a modular device for soil application of digestate. In one working pass the device enables to organize a work enabling evenly spreading the digestate at the soil surface, mixing it and covering with soil. Finite Element Method (FEM) numerical methods have been used for the development of a construction which allowed, among others, the determination of loads at the point of the tools connection. Carrying out experimental research in real conditions of operation, stress distribution and force values occurring in connection were determined. The force values obtained were verified with computer analysis carried out at the 3D model of the device, demonstrating the correctness of the assumptions made.
