Paper Title:
Research of Favorable Conversion of Friction during Powder Compaction
  Abstract

The warm powder compaction process is simulated by the finite element analysis software which is MSC/MARC. The thermal mechanically coupled analysis method is applied based on the updated Lagrangian Method to study the influence of different velocities ratio of die and punch υdie/υup-punch on the properties of green under different frictional condition. The results indicate that for cylindrical powder metallurgic products, different velocity ratios have great influence on the distribution of relative density and equivalent stress. The frictional force can be converted to the favorable force through adjusting the velocity ratio, and this method can obtain higher uniform distribution of relative density and stress of green.
