冲压成型解析方法
摘要：
本发明涉及冲压成型解析方法，该方法具有冲压成型解析步骤、回弹解析步骤以及形状解析步骤。在上述冲压成型解析步骤中，针对加热后的被冲压成型材料设定初始温度分布，并使温度解析和构造解析相结合地进行冲压成型解析，获取冲压成型后脱模前的形状信息、温度分布、应力分布以及应变分布。在上述回弹解析步骤中，基于在该冲压成型解析步骤得到的形状信息、温度分布、应力分布以及应变分布，使温度解析和构造解析相结合地进行回弹解析，获取回弹后的形状信息、温度分布、应力分布以及应变分布。在上述形状解析步骤中，基于在该回弹解析步骤获取的形状信息、温度分布、应力分布以及应变分布，使温度解析和构造解析相结合地解析直至上述被冲压成型材料的温度分布变成±5℃以内的冷却中以及冷却后的形状变化。
摘要（英）：

This press-forming analysis method has a press-forming analysis step, a springback analysis step, and a shape analysis step. In the press-forming analysis step, an initial temperature distribution is set for a material for press-forming that has been heated, the temperature distribution and a structure analysis are combined to perform the press-forming analysis, and pre-mold-removal shape information, temperature distribution, stress distribution, and distortion distribution after press forming are acquired. In the springback analysis step, temperature analysis and structure analysis are combined, on the basis of the shape information, temperature distribution, stress distribution, and distortion distribution obtained in the press-forming analysis step, to perform the springback analysis, and shape information, temperature distribution, stress distribution, and distortion distribution after springback are acquired. In the shape analysis step, shape change during and after cooling, until the temperature distribution of the material for press-forming is within +-5DEG C, is analyzed by combining temperature analysis and structure analysis on the basis of the shape information, temperature distribution, stress distribution, and distortion distribution obtained in the springback analysis step.
