Dynamic FE Analysis of the High-Speed Planetary-Motion Mixer UM-500

In the current paper the results of finite element non-linear mechanical analysis of the energy-saving high-speed planetary-motion mixer UM-500 are presented. The mixer is a system consisting of two milling chambers partly filled with substance to be milled. Milling chambers are in compound motion: rotation about vertical central axis and self-rotation about moving sloping axes. To perform dynamic analysis detailed finite element model is created based on CAD model. Finite element model considers nearly all features of the real construction. By means of LS- DYNA the detailed finite element analysis of dynamic non-linear process of mixer takeoff out of the casing in the result of emergency situation is performed with use of elasto-plastic material model with strain-based failure crite- rion. Dynamic analysis of the rigid-body motion stability of the mixer at speed-up regime is carried out for simpli- fied mathematical models
