Numerical simulation of separation processes in mechanical working

Abstract


The paper deals with the methodological peculiarities of numerical simulation of separation processes in the context of the finite element method. It is shown that a poorly conditioned global stiffness matrix reflects the essence of the separation process. A method for monitoring the reliability and accuracy of the calculated data by means of the spectrum of a non-regularized global stiffness matrix is put forward. The possibility of assessing the spectrum of a global stiffness matrix through the sums of local matrices is shown.
