Sažetak
Wrinkling is one of the most important factors
influencing a forming precision of sheet metal,
which brings difficulties to the forming process of
sheet metal. In order to eliminate the wrinkling
during the forming process, an accurate prediction
is necessary. In this paper, the wrinkling
elimination process was investigated based on the
principle of the Yoshida Buckling Test (YBT) and
viscous pressure forming. The experimental device
was designed, and evaluation method of the
wrinkling elimination rate was presented by the
stainless steel SUS304. On this basis, the wrinkling
elimination experiment was carried out, the
influences of both the viscous medium molecular
weight and the tensile state of wrinkle under the
viscous pressure on the wrinkling elimination were
obtained.
