Embodiment Construction
[0056] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but the content of the present invention is not limited to the stated scope.
[0057] Embodiments of the invention: attached figure 1 It is a method step diagram of the present invention, according to the theoretical relationship between load, displacement and stiffness matrix in the finite element theory, it is deduced that the structure satisfies the corresponding maximum displacement requirement (maximum displacement≤ μ 2 ) under the condition of material Young's modulus calculation formula, and the structure satisfies the frequency f of the corresponding j order j The relational expression of structural material Young's modulus and material density under the condition, the concrete realization step of the inventive method is: step 1, setting structural material is certain arbitrarily known material, and the Young's modulus of this material is E 1 , w...
