Abstract


In this paper, the domestic wrapped bushes industry production process is relatively backward , sleeve products of poor quality precision situation , focusing on the sleeve circle round the forming precision and its influencing factors , bimetallic materials with a focus on using the finite element numerical analysis techniques sleeve turns round molding process simulation study investigated based on several key factors forming precision of affect the bushings circle round . First of all , the domestic and international overview of the development and application of double metal sleeve material is reviewed and summarized ; analysis of the research status of a self- lubricating wrapped bushes and plate forming finite element numerical analysis ; sleeve circle round plastic bending theory forming the deformation process of the systematic theoretical analysis of the bending moment in the forming process of the bimetal bush , the springback process related calculation processing . To discuss the details of the sleeve circle round molding process involves the theory of finite element simulation and software ; analysis sleeve circle the circle forming process simulation in material model , the selection of the unit , the division of the grid , as well as the practical application of the theory of friction contact . Application MSC.Marc finite element analysis software , sleeve circle round molding process detailed simulation analysis of the distribution of the stress and strain of the plate as well as the flow of material deformation . And combined with the actual situation of production , in-depth study of the bi-metallic material parameter selection , circle round mold gap change sleeve rebound , warping and forming precision , parameter optimization suggestions . Create a finite element model of the simulation analysis of this article , the treatment of the boundary conditions , and the conclusion has certain reference value for the improvement of the technology and die design of double metal bearing products to improve the quality of double precision metal bushes .
