| description | The article introduces the comparative model and analytic description of helical implementation of collector method for compacting powder material developed and licensed at Tomsk polytechnic university. The collector method principle is based on density autoalignment throughout the compact by multidirectional movement of mold forming surfaces. Within the principle the authors have proposed the kinematic diagram of sealing cylindrical compacts in the collector mold with spiral slides spun around compaction axis at a certain optimum angle. The authors have proposed the analytic tools for initial analytic study of the compaction diagram efficiency. Powder compaction in different ways was modeled by the finite element method. The results of the comparative simulation showed that statistical variability of deformation local values in compacts made by collector method with spiral slides decreases to 48 % in comparison with common static compaction and to 5 % in comparison with the original version of the collector method. Thus, the collector method with spiral slides allows decreasing additionally density gradients and may be used for manufacturing ceramics of nanopowders which are characterized by pronounced negative effect of wall-adjacent friction at their compaction in closed rigid molts. |
