Then, the result of equation of critical buckling time and diagrams between critical buckling time and drawing coefficient, relative conical radius, relative radius and relative thickness are given by computer program.
然后通过计算机编程 ,求解了临界失稳方程 ,得到了拉深系数、相对锥顶半径、相对圆角半径、材料相对厚度与临界失稳时刻间的关系曲线 ,并对曲线变化的规律进行了分析。
