为了减少薄壁梁架加工变形，应用ANSYS/LS-DYNA软件进行有限元加工仿真，获得已加工表面残余应力，预测梁架加工变形。分析不同切削用量对加工变形量的影响，优化切削用量，进行变形预补偿。在此基础上，对梁架整体加工工艺进行优化。机翼颤振模型薄壁梁架的加工证明该方法可以有效提高薄壁件加工的质量和效率。

In order to reduce the machining deformation of thin-walled frame, finite element simulation soft-ware ANSYS/LS-DYNA is used to obtain the residual stress and deformation. The cutting parameters are adjusted to carry out deformation active compensation. On this basis, the overall machining process is opti-mized. Process of wing flutter model frame prove that this method can effectively improve the quality and efficiency of machining of thin-walled parts.
