In this research, results of experimental investigations and physical model were used as the input variables for numerical analysis of the ironing strip drawing process by application of lubricants. The numerical simulation was realized in the specialized applicative software Simufact.forming. By applying the software for the 3D modeling, a model of the tool element assembly was made, which served as the starting basis for numerical simulation by application of the Finite Element Method. Experimental values of the friction coefficient for each type of lubricants and the contact pressures were used for defining the contact conditions. Numerical simulation of the drawing process was done for each type of the contact conditions between the tool's elements and the thin sheet sample. After conducted tests comparison of experimental and numerical results of the drawing forces in different contact conditions was done. Comparison was done with taking into account appearance of galling due to difficult drawing process conditions. By comparation of numerical results to the experimental one it is possible to interpret what types of simplifications were adopted in creating the experimental physical-tribological model. |
