“…6 reflects the change process of stamping sheet metal forming force，which is the relationship between the forming force and the corresponding time step. The right press equipment, that is, press for stamping can be choosed by the curve [3][4]. In the next figure, the 20_punch and 20_punch maximum drawing force are 4900N.…”

Punching bonding made for study context and Autoform selected for platform, numerical simulation of stamping was carried under different shapes, different materials, different parameters, and the different simulation results was gained . And deformation, the thickness of the forming limit analysis of simulation results, etc., and thus such important parameters as the thickness of sheet metal, punch diameter, the speed and the size of power punching and etc.,was modified and debuged, the combination of optimized process parameters of sheet metal was achieved in the final. Therefore, AutoForm not only can be used to overcome the difficulties,which there is no standard available, relying on repeated experiments to determine the parameters of the connected so as to achieve green design stamping; but also be made for stamping die design and production of connections to increase the efficiency and the expansion of the stamping connections the scope of the application.

Molecular dynamics simulations and free energy calculations were employed to investigate the evolution, formation probability, detailed balance and isomerization rate of small C cluster isomers at 2500 K. For C 10 , the isomer formation probability predicted by free energy is in good agreement with molecular dynamics simulation. However, for C 20 , C 30 and C 36 , the formation probability predicted by free energy is not in agreement with molecular dynamics and the detailed balance does not hold, indicating that the molecule system is in non-equilibrium. Such result may be attributed to the transformation barriers between cage, bowl and sheet isomers.
