Numerical Simulation of Hydroforming Process for Thin Products

Abstract

     Metal forming is a basic mechanical industry. It allows the manufacturing products with complex shapes and size. Hydroforming process is a special drawing method. In the last years, this method is often used for forming of thin products with complicated geometry in the airplane and automotive manufature, because it has many advantages compared with conventional deep drawing process. Nevertheless, at present in Vietnam the hydroforming design is largely based on the experience. In this paper, the author apply software Eta/Dynaform for simulation ò the hydroforming process of thin product to optimeze the deep drawing hydroforming process.
