Abstract:

Based on uncertain deformation and low robustness of sheet metal deformation, considering noise factors, the influences of random variations were studied. The control factors were as the numbers and positions of the locating points, the sizes and areas of the extend forces. The noise factors were as fixture variations and material variations. Descriptive sampling was applied to random noise factors. Through DOE and finite element simulation, the effective deformations and response windows in all levels were obtained. The goal control strategy might be obtained by analyzing the above data. The examples indicate that the analysis method can successfully analyze and solve the problem of the robustness of sheet metal deformation when considering noise factors. So, the method provides an important and significant idea to reduce the deformation and improves the robustness of sheet metal.
