Abstract

Critical for flanging of square tributary junction on cylindrical steel tube is to determine the shape and sizes of pre-machined hole. In order to investigate precise shape and sizes of the pre-machined hole, an optimized design model is established. The forming process during flanging is simulated with the aid of FE-simulation software, and the target function for optimized design is calculated based on results of the simulations. In order to increase the convergence rate of the optimized design, a mathematical model of pre-machined hole for flanging on the tube is established based on isoline theory, the results are used as initial values for optimized design. To verify its accuracy the optimized design is carried out based on a typical flanging of square tributary junction on cylindrical steel tube. The results of the optimized design meet the technological requirements.
