STUDY ON INFLUENCE OF PROCESS PARAMETERS ON THE WALL THICKNESS DISTRIBUTION OF PART IN SHEET HYDROFORMING PROCESS FOR THE PARTS OF SPACE

Mechanical Engineering, Material Science

This paper presents the results of a numerical simulation study on the influence of process parameters on the deformation ability in the sheet hydroforming process for the parts of space. Deform 2D software is used in numerical simulation. Process parameters studied include forming pressure (q), radius of die (R), and speed of axial press of punch (v). Deformation ability is assessed through the degree of thinning of the wall thickness Δs (%). First, the response surface method (RSM) is performed to examine the relationship between the output and the input. Then, an analysis of variance (ANOVA) was conducted to verify the response significance and influence of the parameters. Finally, an optimization algorithm is used to determine the optimal set of process parameters. The obtained results allow analysis and selection of reasonable process parameters in the sheet hydroforming process for the parts of space, serving to manufacture complex parts for industrial applications.
