Abstract
This study focused on the installation of small hopper inserts designed for mass flow. An FEM-“Silo-Flow-Program-System” was used for the calculations. Using full-scale silo experiments, the loads on the “cone in cone” inserts were measured as a function of the installed positions. The results obtained from all experiments and in the numerical simulation showed a rise of the vertical loads on the hopper inserts as the height position increased. The comparisons between experiment and calculation with the more complex material law variant show relatively good agreement, above all for the lower to middle height positions. The load increases as a function of the height position are reproduced well by the numerical simulations. The summarizing representation of the experimental built-in loads for the three hopper inserts shows an approximately linear dependence of the vertical load on the height position for emptying.
