Abstract

The method of stamping by an elastic medium is known for a long time and everywhere, and in favor of its further application, proves developments that allow the intensification of the stamping process by an elastic tool. Among these areas of improvement, the computer simulation of the process is particularly promising, which allows you to determine the energy-power parameters of the process, the behavior of the material throughout the process, as well as the stress-strain state of the workpiece, which allows you to shorten the time further in the development of processes for typical parts, as well as significantly reduce the cost of materials to conduct a series of experiments, reduce the complexity and time of technological preparation of production. It is this method as the most suitable for improving the stamping process at the current stage of development of domestic production, considered in this paper on the example of bending-molding sheet material. To solve the problems of forming, carried out in this work, the most rational is the use of the variation method or the FEM method. Both of these methods provide fairly accurate results, however, the advantage of FEM is its high applicability in various computer software products such as Nastran, Ansys, Katy, etc., which allows to optimize the process of obtaining data by reducing the calculation time, as well as the most optimal the ability to make changes and adjustments to the process without the need to spend time on manual recalculation.
