摘要: 常规方法设计出的钛合金稳定化工装厚重,验证周期长。通过研究TA15钛合金的高温拉伸和蠕变行为,建立钛合金高温持久寿命有限元模型,模拟高温受载荷状态下的工装变形情况,实现对工装结构的优化。结果表明,通过蠕变试验结果,结合数据分析软件中的Allometric1函数,TA15钛合金的蠕变本构方程为:ε·=7.411×10-8σ2.759。利用ABAQUS准静态分析模块及TA15钛合金的蠕变本构方程,可进行TA15钛合金稳定化工装的校验,为其优化设计提供依据。

Abstract: Stabilizing treatment fixture for titanium alloy designed by conventional methods is thick and heavy, and the verification cycle is long. By studying the high temperature tensile and creep behavior of the TA15 titanium alloy, a finite element model of the high temperature rupture lifetime of titanium alloy was established to simulate the deformation of the fixture under high temperature loading conditions and optimize the fixture structure. The results indicate that based on the creep test results and the Allometric1 function in the data analysis software, the creep constitutive equation of the TA15 titanium alloy is ε·=7.411×10-8σ2.759. The ABAQUS quasi-static analysis module and the creep constitutive equation of the TA15 titanium alloy can be used for the verification of stabilizing treatment fixture, providing a basis for its optimization design.

Key words: finite element analysis, high temperature creep, stabilizing treatment fixture, verification module
