Optimization and Analysis of Hydroforming Process for Four-way Pipe

Journal of Harbin University of Science and Technology, 2018
Based on Dynaform, a finite element model of hydroforming for four way pipe was built. Through the initial feed rate, initial internal pressure, and the intermediate pressure were selected as the design variables, taking the minimum and maximum wall ...

Electromagnetic Compression as Preforming Operation for Tubular Hydroforming Parts [PDF]

, 2004
With the aim to extent the forming limits of tube hydroforming a concept of using a previous electromagnetic compression operation will be introduced. One important limit for the possibilities of tube hydroforming is set by the initial circumference and ...
