THREE-DIMENSIONAL FINITE-ELEMENT SIMULATION OF STRETCHING TECHNOLOGICAL PARAMETERS bt/h AND bb/h OF HEAVY FORGINGS
摘要
A three-dimensional finite-element simulation of stretching technological parameters of heavy forgings is performed by using ANSYS program. The law of internal stress distribution with different bt/h (tool width ratio) and different bb/h (blank width ratio) is studied. Consequently, the critical tool width ratio( bt/h )cr and blank width ratio( bb/h )cr leading no bi-axial tension are obtained. It lays a credible foundation for designing reasonable stretching technology.
