【Abstract】 By using the FE-simulation technique instead of the traditional research method,more than 500 tube-drawing process simulation tests with the computer are carried out based on a great variety of technological parameters,so that a number of problems,such as cross/longitudinal cracks and tube geometrical variation are researched,a mathematical model of over 100 various crucial parameters are achieved,and a CAD system for tube cold-drawing process developed.更多还原
