    摘要: The present invention enables a shape of an optimum structure to be clearly represented, and structural optimization having a high degree of freedom such as the allowance of a change in topology in a material domain Ω to be performed. The present invention sets a level set function φ; under a predetermined constraint condition, updates the level set function φ so as to bring a performance of a structure, such as a rigidity, close to a target value; moves a boundary ∂Ω between the material domain Ω and a void domain; allows a change in topology in the material domain Ω, which is associated with the update of the level set function φ, to form a new void domain in the material domain Ω; and moves a boundary ∂Ω between the new void domain and the material domain Ω.

    摘要: The present invention enables structural optimization having a high degree of freedom, such as the allowance of a change in topology in a material domain Ω, and provides clear expression of the shape of optimum structures. The present invention defines a level set function φ; updates the level set function φ, under a predetermined constraint condition, so as to bring a performance of a structure, such as a rigidity, close to a target value; moves the boundary ∂Ω between the material domain Ω and a void domain; allows a change in topology in the material domain Ω, which is associated with the update of the level set function φ, to form a new void domain in the material domain Ω; and moves the boundary ∂Ω between the new void domain and the material domain Ω.

    摘要: The optimal design support system is to design a structure that outputs a desired load or displacement to a portion by using elastic deformation when a load or displacement is applied to a predetermined portion. More specifically, the optimal design support system comprises a structure creating part 11 that creates a structure FM as being an integrated structure of multiple mutually different types of elements by changing a material layout within a design domain D so as to minimize the difference between the output load or displacement and the desired load or displacement and to maximize the stiffness of the object globally, an initial shape setting part 12 that sets a feasible initial shape IS corresponding to the function of each element which forms the structure FM, and a shape changing part 13 that changes the initial shape IS so as to minimize the difference between the displacement, the load, a related stress or a related strain and a predetermined target value within a range where any parts of the initial shape IS deforms elastically.
