| The aim of the work was to successfully obtain qualified products in the lest times of experiment. The heavy commercial vehicle axle forming process and die was designed， and then the finite element simulation was carried out.According to the difficult problem of long product development cycle and large cost of precision roll forging-die forging， the study improved the roll forging method. Combined FEM and physical experiment， verified the feasibility of block design. By adopting sectional design method， the test times could be significantly reduced and quickly produced qualified products， finally could provide guidance to the actual production. |
