Abstract

The paper indicates the relevance of forming initial data for studying the stress-strain state of a cargo platform using discrete element (DEM) and finite element (FEM) methods. The article provides a set of calculated cases that account for critical operating conditions (overload, load displacement, hydraulic cylinder failure, sticking, dynamic braking). A system of boundary conditions is described in detail, simulating real attachment points of the cargo platform. Attention is given to the method of converting and transferring load data (nodal pressures) from the DEM model to the FEM grid, including interpolation issues in case of grid mismatches. The developed initial data enable comprehensive strength analysis and identification of critical areas of the structure at early design stages.

Keywords
