The choice of the kinematic scheme of formoobrazovany by stretch forming of obvodoobrazuyushchy covers of the difficult spatial form

Abstract

The choice of the kinematic scheme of formoobrazovany by stretch forming of obvodoobrazuyushchy covers of a difficult spatial form depends on the angular values connected with a corner of coverage of an obtyazhny punch by preparation and with a corner of unbendingof a cover between operations of consecutive covering.Researches were carried out by means of the final and element analysis in the program ANSYS/LS-DYNA environment for a cover with concrete geometrical characteristics. By results of research the choice of one of three kinematic schemes was carried out.
