Loading Path Determination for Tube Hydroforming Process of Automotive Component Using APDL
In this study, an extended stress-based forming limit diagram (FLD) for prediction of necking based on the Marciniak and Kucznski (M-K) model is represented and applied in tube hydroforming. The bulge forming of a straight tube is simulated by finite element method and verified with published experimental data. This adaptive simulation technique is based on the ability to detect the onset an...
متن کاملReliability analysis of tube hydroforming process
In this paper, we propose a reliability–mechanical study combination to treat the tube hydroforming process (THP). This process consists to apply an inner pressure combined to an axial displacement to manufacture the part. Our goal is the computation of the failure probability of the hydroforming process. Normally, this process is particularly complex and have to be solved numerically. There ar...
متن کاملSimulative Analysis of Tube Hydroforming Process
The tube hydro forming process (THF) is an unconventional metal forming process, where in tube is deformed internally and thus it is forced to expand and conform to the shape of the surrounding die. The performance of this process depends on various parameters like internal pressure, axial loading etc. For FEA simulation, it requires proper combination of material selection, part design and bou...
متن کاملNumerical Study on Effect of Bilinear Pressure Path on Corner Filling in Hydroforming of Tube in Box-Shape Die
Die corner filling is very important in tube hydroforming process. Definition of the internal pressure path is a key factor in improving the corner filling. However, the factors that cause improvement of corner filling are still unclear. In this paper, effect of bilinear pressure path on corner filling in hydroforming of tube in box-shape die is studied using both finite element simulation and...
متن کاملDatabase for real-time loading path prediction for tube hydroforming using multidimensional cubic spline interpolation
Tube hydroforming (THF) is ametal-forming process that uses a pressurized fluid in place of a hard tool to plastically deform a given tube into a desired shape. In addition to the internal pressure, the tubematerial is fed axially toward the die cavity. This process has various applications in the automotive, aerospace, and bicycle industries. Accurate coordination of the fluid pressure and axi...
