用上限法解中心对称锥形模正挤压零件的问题

Solution for Centrosymmctric Conical Die Forward Extrusion Problem Using UBT

对于中心对称横截面零件的正挤压问题变形力的求解,作者将该变形体划分成若干个(例如m_1个)过中心的纵截面,就此纵截面将其当作轴对称问题求解,然后取其算术平均值。文章最后求解了一种六角花形扳手正挤压的变形力。

The deformation force in the forward extrusion is solved to the controsymmetric trausoction Part.Author divide the deformation body into many through lengthwises, which were solved as axisymetric problem, and then evaluate their arithmetic mean, and finally a deformation force is solved to a hexagon spanner as an example.
