Hydroforming High Strength Steel Tube for Automotive Structural Applications
The need for lighter, stronger, more rigid vehicle structures will increasingly require complex hydroformed structural tubes to increase strength, and decrease weight, cost and part count. This effort will increase the use of high strength, low alloy (HSLA) steel, in place of SAE 1006/1008 or 1010 steel. Traditional hydroforming techniques require the higher elongation of […]
Introduction to the Hydroforming Processes
To try to answer some of the most important global demands of current designs, such as economic efficiency of technical solutions, careful handling of energy and raw materials, optimized work-piece properties innovations in processes and approaches, near to more conventional solutions, are developed. Moreover it is to consider that the increasing technological demands concerning the […]
Optimization of a Tube Hydroforming Process
An approach is presented to optimize a tube hydroforming process using a Genetic Algorithm (GA) search method. The goal of the study is to maximize formability by identifying the optimal internal hydraulic pressure and feed rate while satisfying the forming limit diagram (FLD). The optimization software HEEDS is used in combination with the nonlinear structural […]
