| Abstract: | Computer numerical simulation of rectangle aluminum section extrusion process is carried out using rigid plastic finite element method, and the key techniques of it are studied. The result agrees well with that obtained by physics simulation to measure the metal particles flowing condition in extrusion process by extruding different color plasticines. Proves the correctness of computer numerical simulation. The result provides the theoretical base for establishing reasonable aluminum section extrusion process variables and die designing. |
