摘要
为获得钛合金孔冷挤压后回弹量,提出基于弹塑性理论的幂强化材料孔冷挤压后回弹量计算方法。将TC4钛合金孔冷挤压后回弹量的试验测量结果与理论模型计算结果进行比较,验证了模型的准确性,同时利用模型分析了挤压量和初孔直径对TC4钛合金孔冷挤压后回弹量的影响。
In order to get the springback of cold expanded holes in titanium alloy,the calculation method of springback of cold expanded holes in power hardening material is proposed based on the elastro plastic theory.The theoretical results of sptingback of cold expanded holes in TC4 titanium alloy are compared with the experiment measurement results,which show that the model is accurate.Besides,the springback effects of expansion degree and existing hole diameter in TC4 titanium alloy are also analyzed based on the model.
