Fast Multipole Boundary Element Method in Rolling Engineering and its Research Progress
The FM-BEM and its research progress in rolling engineering are systematically introduced. At first, the principle and mathematical theory of the FM-BEM is demonstrated. Secondly, numerical computations for the FM-BEM are analyzed. Some fundamental functions and formulae are constructed for the boundary surface. An optimization mathematical model is established for the elastic and elasto-plastic frictional contact system. Practical and efficient solution strategies and algorithm are presented. Thirdly, some applications of FM-BEM in large-scale rolling engineering are presented, which includes the simulations of roll shape, stand stress, assembly process of the oil film bearing tapered sleeve and roll neck, reliability of the 3500mm mill pressure screw-pairs, and cold-rolling process of 2030mm four-high mill. Finally, the development trend and some problems to solve are discussed.
