为实现TB8钛合金长包边零件的高效精密成形，提出一种结合预成形与高频感应快速应力松弛的复合成形工艺。通过建立电磁-热-力多场耦合有限元模型，系统模拟了不同感应热源移动速度下的温度分布、应力松弛与回弹行为，并开展了包边试验件成形验证。研究结果表明，随着感应热源移动速度的提高，成形件两侧回弹误差逐渐增大。当移动速度为0.7 mm·s-1时，左右两侧最大回弹误差分别为0.48和0.23 mm,满足零件成形误差±0.5 mm的设计要求，显著提高了成形精度与效率，证实了预成形/高频感应加热复合成形工艺在TB8钛合金包边快速精密成形中的可行性与有效性。
Abstract：To achieve efficient and precise forming of TB8 titanium alloy long-edge components, a composite forming process combining pre-forming and high-frequency induction rapid stress relaxation was proposed. An electromagnetic-thermal-mechanical multi-fields coupling finite element model was established to systematically simulate the temperature distribution, stress relaxation and rebound behavior with different induction heat source moving speeds. Forming validation was conducted on edge test specimens. The research results indicate that as the induction heat source moving speed increases, the rebound errors on both sides of the formed part gradually increase. When the moving speed is 0.7 mm·s-1, the maximum rebound errors on the left and right sides are 0.48 and 0.23 mm, respectively, meeting the design requirement of ±0.5 mm forming error of components, significantly improving the forming accuracy and efficiency, thereby confirming the feasibility and effectiveness of the combined preforming/high-frequency induction heating process for the rapid and precise forming of TB8 titanium alloy edges.
