Numerical simulation of new ring rolling process of tubeless steel wheel

Finite element analysis of maximum rolling pressure of rotary roll forming for straight tooth bevel gear;

By using some simplification assumptions,a theoretical analysis of the local rolling forming load for the discal parts is presented.

Kinematical analysis in ring rolling;

This paper introduces the whole process of the hot rotary forming for automobile s half shaft, especially introduces the gathering materials procedure by oil hydraulic press before the hot rotary forming.

By comparing the microstructures of rings before and after deformation and measuring the values of microhardness after heat treatment,the effects of cold ring rolling deformation on microstructure of rings and its mechanical property after quenching and tempering were discussed.
