摘要
针对风扇盘材料的本构模型进行参数辨识,为使有限元模型的模型上有准确的加工应力场进行贴合,对TC11钛合金残余应力进行经验公式的建模,开展残余应力仿真方法研究。对风扇盘半精车小端进行仿真建模与验证。基于残余应力仿真结果进行工艺参数优化,通过实例加工验证了方法的有效性。
The parameters of the constitutive model for fan disk material are identified.In order to fit the finite element model with accurate stress field in the machining,the empirical formula of residual stress of TC11 titanium alloy is modeled,and the simulation method of residual stress is studied.The simulation modeling and verification are carried out on the small end of the fan disk semi-finishing turning.The processing parameters are optimized based on the simulation results of residual stress,and the effectiveness of the method is verified by an example.
