| 摘 要： | 在研究薄板冲压成形原理和模型描述的基础上,采用ANSYS有限元方法对钛合金板材翻边成形进行了系统的分析,完成对钛合金板材的室温和高温下的翻边成形过程的模拟,预测板材成形过程中的应变分布,并得出室温和高温下极限翻边系数,预测值与试验值相比较,拟合良好,同时应变分布规律符合试验结果,证明了有限元方法模拟钛合金热成形性的可行性和准确性。

| Abstract: | On the bases of the sheet stamping theory and stamping model,the finite element analysis of titanium alloy sheet flanging process was carried out by ANSYS software,the flanging process simulation in room temperature and higher temperature has been achieved and the flanging process strain distribution has been simulated.We have got the margin flanging coefficient.The predicted results and the measured values are fitting well,and the strain distribution rule accords with the test result,which validates the veracity of the finite element analysis method sufficiently. |
