Abstract
The three-dimensional models of the Working-roll of Carder are founded by three-dimensional design software Solidworks and the working process of Working-rolls is simulated by finite element analysis software Cosmos, which obtain overall stress distribution for the Working-roll of Carder. The relations between the working-rolls with different thickness and different length of work roll axis and the stress, strain and radial displacement in the working process of working-rolls are attained by finite element analysis and the important factors of impact of work roll deformation are indicated by analog simulation. The results show that the maximum stress and maximum strain are occur in the place of roller connected with the axis rather than to appear in the middle part of roller and the radial displacement in the working process of working-rolls and the length of work roll axis are not directly relationship. The Finite element analysis results provide an important theoretical basis to design a reasonable the length of axis and the thickness of roller for the working-roll of carder.
