Warm Pressing of the Gearbox Synchronizing Ring of Belarus Tractors: Computer Modeling

Abstract

The method of computer modeling has been used to study the worm pressing of complex parts based on iron powders. The main relationships of the plasticity theory of porous bodies are used in the framework of the finite-element method. The effect of the ratio between the speeds of different parts of the punch on the density distribution is analyzed. The possible nonuniformity of the density distribution is due to external friction and complex shape of parts. The optimal ratio is found. All other speed ratios of pressing elements lead to unacceptable distribution of properties of powder parts..
