摘要：

?通过回弹前后成形件与模具之间的相对几何关系，精确计算了回弹前后弯曲角度变化情况；基于有限元法，建立了钛-铝-不锈钢层状复合板V型弯曲成形及回弹有限元模型，并将有限元模拟结果与试验结果进行对比，验证所建模型的正确性，并研究了各异质层材料参数波动对复合板弯曲回弹的影响规律。结果表明，回弹角随不锈钢层和铝层强度系数增大而增大，随应变硬化指数增大而减小，随钛层强度系数增大而减小，随应变硬化指数增大而增大，随各异质层弹性模量增大而减小。结合多因素敏感性分析方法，对材料参数波动影响弯曲回弹规律进行了敏感性分析，发现钛层材料参数改变对复合板回弹角的影响最为敏感。

Through the relative geometric relationship between forming part and die before and after springback, the bending angle changes before and after springback were calculated accurately, and the finite element models of Vbending and springback for titaniumaluminiumstainless steel laminated composite sheet were established based on finite element method. Then, the finite element simulation results were compared with the experimental results to verify the correctness of the mode, and the influence of material parameter fluctuation of different heterogeneous layers on the bending springback of laminated composite sheet was studied. The results show that the springback angle increases with the increasing of strength coefficient of stainless steel and aluminium layers, decreases with the increasing of strain hardening index, decreases with the increasing of strength coefficient of titanium layer, increases with the increasing of strain hardening index, and decreases with the increasing of elastic modulus of each heterogeneous layer. Based on the multifactor sensitivity analysis method, the influence of material parameter fluctuation on the bending springback was analyzed. The results show that the change of titanium layer material parameters is most sensitive to the springback angle of composite sheet.
