Reference number : GC-2017-Q2-00043, amendment number : , agreement type : G, recipient legal name : Green, Daniel (University of Windsor), recipient country : CA, recipient province : nan, recipient city : Ontario, recipient postal code : nan, program name english : Engage Grants for Universities, program name french : Subventions d'engagement partenarial pour les universités, program purpose english : In order to reduce the weight of passenger vehicles, more and more sheet metal parts are being made from_x000D_
aluminum. And in order to improve the formability of aluminum, some automotive panels are being formed_x000D_
slowly at high temperatures (around 450ºC): this superplastic forming process allows large, lightweight_x000D_
automotive parts with complex features to be manufactured. While superplastic forming of aluminum is_x000D_
leading to significant weight savings, it remains a slow process._x000D_
The aim of this research project is to evaluate the potential for improving the superplastic forming of aluminum_x000D_
automotive panels by superimposing a vibration on the sheet material while it is being deformed. AEM Power_x000D_
Systems Inc., in collaboration with the University of Windsor will carry out some experimental tensile testing_x000D_
of aluminum sheets at superplastic temperatures with and without superimposed vibrations, and the maximum_x000D_
deformations that can be achieved will be recorded in both cases. Based on the known benefits of vibrations in_x000D_
other sheet metal forming processes, it is anticipated that an improvement in formability will be observed._x000D_
In a second phase the amplitude and frequency of the superimposed vibration will be varied, and the influence_x000D_
of each parameter on the maximum deformation achieved will be investigated. Finally, the analysis of the_x000D_
experimental data will help to identify the optimum combination of amplitude and frequency._x000D_
The third phase of this project will be to develop a preliminary numerical model of this superplastic forming_x000D_
process that does not include the effect of the vibrations. The development of the numerical model to include_x000D_
the effects of vibration are beyond the scope of this 6-month project, however, it will be important in the future_x000D_
to extend the collaboration beyond this preliminary investigation so as to develop & validate a reliable finite_x000D_
element model for the simulation of industrial superplastic forming with superimposed oscillations._x000D_
It is anticipated that this research will give AEM Power Systems Inc. the knowledge and ability to reduce the_x000D_
costs and the cycle time associated with the superplastic forming of aluminum automotive parts., program purpose french : In order to reduce the weight of passenger vehicles, more and more sheet metal parts are being made from_x000D_
