Warm compaction of the gearbox synchronizing ring of Belarus tractors: computer simulation

Computer simulation has been used to study the warm compaction of complex powder parts. Relations of the plasticity theory for porous bodies and finite-element method are employed. The effect of the velocity ratio of different pressing elements on the density distribution is analyzed. The possible n...

Zusammenfassung:	Computer simulation has been used to study the warm compaction of complex powder parts. Relations of the plasticity theory for porous bodies and finite-element method are employed. The effect of the velocity ratio of different pressing elements on the density distribution is analyzed. The possible nonuniformity of density distribution is due to external friction and complex shape of parts. The optimal ratio is found. All other velocity ratios of pressing elements lead to unacceptable distribution of properties in powder parts.
