Використання ліній току для визначення кількості переходів при гідродинамічному моделюванні витяжки глибоких коробчастих виробів із листового металу
The extract of hollow products which have no axial symmetry is considered. Possible variants of construction of lines of a current on known ekvipotential to lines are considered some. Nonlinear systems of the equations which consist of the equation ekvipotential lines and lines of a current which can be solved iterative methods are made, and current lines in a half-finished product flange are constructed. The method of construction of orthogonal lines to the set pieces by means of applied programs of an engineering computer drawing is considered.
