压力机的强度计算、刚度计算、模具在工作过程中的应力分布以及材料在模具中的流动规律等,都是研究锻压设备、模具及工艺过程的重要课题。采用传统方法进行计算,需要大大简化边界条件和压力机及模具的几何形状。这种方法很难得出准确的计算结果。进行模型试验,不仅所需周期长,费用高,而且测试结果也往往因为精度低而不能令人满 Press strength calculation, stiffness calculation, the mold in the work process of the stress distribution and the flow of materials in the mold, etc., are forging equipment, mold and process an important issue. The traditional method of calculation requires greatly simplified boundary conditions and the geometry of the press and die. This method is difficult to draw accurate calculations. Model tests do not only require long periods, high costs, and test results are often not as full due to poor accuracy
