Title:
The manufacturing method of an airplane structure, a preparation method of the design information of an airplane structure, a design system of an airplane structure, and a design program of an airplane structure
Document Type and Number:
Japanese Patent JP6085324
Kind Code:
B2
Abstract:
According to one implementation, a method of making design information of an aircraft structural object, executed by a computer, includes: setting at least one parameter as a variable for an optimization calculation which minimizes a weight of the structural object composing an aircraft; setting at least one allowable range for at least a strength of the structural object corresponding to the at least one parameter; and calculating an optimal value of the weight of the structural object and a value of the at least one parameter by the optimization calculation. The at least one parameter expresses the design information of the structural object. The at least one allowable range is set as at least one constraint condition of the optimization calculation. The value of the at least one parameter corresponds to the optimal value and meets the at least one allowable range.
