    Abstract
  • This paper systemic investigates the fitability of the notched panel with double curvature by FEM method. The FEM simulation model was established for analysing the fitability of the notched panels on discrete nails die. Further more,the effect trend of the notch parameters,such as deep and width,on the precision of the panels was analyzed. The most important factor is the relatively deep of notch. Optimize parameters of notch was found by simulation. It provide the solution for the precise forming of notched panels with double curvature. Both the simulation results and the experimental validation show that the notching technology can achieve the precise forming of doubly-curved reflector panels with continuous surface.
