Elastic Cushion

As a flexible manufacturing technique, Multi-point stretch forming (MPSF) is a suitable method for forming aircraft outer skin part. The traditional solid stretching die is replaced by the discrete multi-point die (MPSD), and the sheet metal is stretch-formed over the MPSD generated by serial adjusting mode or parallel adjusting mode. The MPSF can be used to form the parts of different shape and reduce the cost and leading time of stretching die fabrication for aircraft outer skin part. A series of numerical simulations on typical MPSF processes of aircraft outer skin part were carried out. The thickness of elastic cushion and free length are important factors to influence on the stretch forming results of stretch-formed parts. The numerical simulation results show that the thicker the elastic cushion is, the more valid the dimple will be suppressed .The longer the free length is, the easier the wrinkle will be brought.

Inner Pressure

Air bulge forming is a forming process where an inner pressure deforms the material to the shape of a die cavity. The main concerns about such a process of profiled cans are to avoid wall thickness reduction, wrinkling and bursting. The success of this process strongly depends on the choice of process parameters, i.e. the properties of material, thickness and inner pressure. By transforming the problem into a deformation controlled rather than a force controlled process, the results from the process parameter estimation become more reliable but on the other hand less intuitive. In this context, the influence of materials, friction coefficient, transitional fillet radius, thickness and bulging load are studied and some suited technological parameters and forming rules are obtained. The most important point is that the simulation and results of experiments are probably consistent.
