Abstract：

The generally used material models in formation simulation of wrapped bearing bushes are introduced in detail,and the finite element models are established in this paper based on MSC/Marc software package.The analysis on model simulation is conducted by using different material models.Compared with the data from actual work,it is evident that different material models result in different precisions.Hence,it is necessary to choose a proper material model in accordance with specified requirements,which offers references to the better understanding of mechanics in the wrapped formation and the selection of material models.
