Geometrical defects correction of stamping parts by numerical simulation and design of experiment
نویسندگان
چکیده
A method of correction and optimization of stamping processes is proposed. The experiment design and finite element methods are interfaced. This is applied on a part showing large springback. After the determination of the important process parameters to study, a fractional factorial experiment design is built and the corresponding numerical simulations are carried out. Their results are the deformed meshes which are post processed in order to measure the virtual part geometry. Linear mathematical relations between the part geometry and process parameters are established and allow to determine their influence and their interactions on the geometry part shape. Finally those mathematical relations enable to find good values for the process parameters which lead to the expected part geometry.

متن کاملA New Technique based on Strain Energy for Correction of Stress-strain Curve
Tensile stress-strain curve is of high importance in mechanics of materials particularly in numerical simulations of material deformations. The curve is usually obtained by experiment but is limited by necking phenomenon. Engineering stress-strain curve is converted to true stress-strain curve through simple formulas. The conversion, however, is correct up the point of necking. From this point ...
متن کاملA Low Cost Numerical Simulation of a Supersonic Wind-tunnel Design
In the present paper, a supersonic wind-tunnel is designed to maintain a flow with Mach number of 3 in a 30cm×30cm test section. An in-house CFD code is developed using the Roe scheme to simulate flow-field and detect location of normal shock in the supersonic wind-tunnel. In the Roe scheme, flow conditions at inner and outer sides of cell faces are determined using an upwind biased algorithm. ...
