Three-dimensioned extrusion simulation and analysis of bending aluminum-alloy tube based on Deform software

摘要：

In this paper three numerical models , eccentric extrusion method to prepare bending tube ,concentric partial material extrusion method to prepare bending tube, differential velocity extrusion method to prepare bending tube , are built and simulated . Furthermore analyses distribution of material flow velocity filed, load prediction, distribution of simulated tube wall thickness and so on. Though analysis and verification, we can draw the conclusion that three kinds of process methods are feasible, and avoid the quality defect caused by the traditional manufacturing method such as non-uniform wall thickness and wrinkling .They will have practice directive significance for improving bending tube.
