Large Profiled Mesh Reinforcement Bar Rolling Finite Element Simulation Of The Forming Process

In the paper, we simulated the processes of profiled screen cloth bar by ANSYS/LS—DYNA, processing law was revealed , and new experimental method which had signification for both in theory and in practice was realized.We firstly overviewed that the development of processing technique, circumstance of the research progress and large and different type screen cloths at home and abroad, basic theory of finite element simulation (FEM) and main step of FEM simulation during rolling processes by ANSYS/ LS-DYNA were introduced. We focused our discussion on how the parameters including rolling temperature, rolling velocity and friction coefficient etc affected the process of regular roller (oval) and the non- regular roller( the roller of ex- finished product of the A type screen cloth bar ) , and revealed that the distribution of deformation, the equivalent stress and equivalent strain and the vary of dimension of rolling piece under different rolling condition.Finally, according to related regulation and practice, the structure and size of hole type in the process of three different cross section screen-cloth-bar models was improved, and we carried out finite element simulation of this process , got regulations of deformation, the stress and strain regulation and four cross section charts of pass in the last four steps. Compared with the results of experiment, the simulated results were close to it and thus verify the reliability of theoretical analysis.From the paper, we can obviously conclude that the finite element method software like ANSYS have noted effects and foreground in numerical simulation. Finite element technology can quickly simulate real-time movement process of analytic model, which can greatly reduce expensive and time-consuming manufacture of analytic model and test stage. Meanwhile, this paper supplies methods and applying experience for application of finite element in the process of new products development,and supplied effective methods for shortening the period for developing new products, reducing development costs and improving products quality.
