The finite element simulation of SRTC1 pickling steel plate deep drawing was carried out based on Hill' 48, Barlat' 89 and BBC-2005 anisotropic yield models by using Autoform software, respectively. And the numerical simulation of ear height and thickness distribution were compared with the test results. The influence of yield model on the simulation of deep drawing forming of pickling steel plate was studied, The optimal yield model was obtained. The results show that the relative errors between ear height difference of the deep drawing forming steel plate cylindrical part simulated by Hill' 48, Barlat' 89 and BBC-2005 yield models and test results were 16.20%, 11.27% and 7.74%, respectively. The relative errors of the maximum thickness difference between the simulated results and the test results were 8.28%, 5.25% and 2.30%, respectively. The BBC-2005 yield model had the highest prediction accuracy in both the ear height and thickness distribution because of the consideration of the stress and deformation anisotropy parameters of the material.
