Assuming that a linearly elastic material,small strains and displacements and a time harmonic exp(-iωt) dependence but without considering external traction,variational model of elastodynamics[11] is shown as: ∫vδέTбdV－ω²∫vδũTρũdV=0 (11) for any kinematically admissible trial displacement field δũ=[δur,δuθ,δus]T.The ρ is density and ∫v·dV is volume integration of the element.

In the rolling process, there are definite relations in the following factors: the strip steel rolling time and material, blanks and finished product specifications, tapping temperature, thickness and plate length.
Figure 2 Width specifications schematic diagram of arrangement According to the data given above conclusions, in order to save energy, reduce the preparation time the manufacture plan arrangements should be first prepared in advance on the specifications of the strip, as far as possible to optimize the type of strip material, if possible, it is best to use the same kind material strip.
