PROBLEM TO BE SOLVED: To provide an optimal component pick-up method for picking up an optimal component in which anisotropic information is set, in an analytical model, taking a component pick-up direction of a blank material into consideration and the board thickness is also taken into consideration.SOLUTION: An analysis method for a metal pipe 1 includes an analytical model generation step S1 for generating an analytical model 7 by dividing the shape of a molded metal pipe 1 into a plurality of elements e, a deployment line setting step S2 for setting a deployment line 9 from one end to the other end in the analytical model 7, a deployment blank shape acquisition step S3 for acquiring a deployment blank shape 11 by deploying the analytical model 7 along the deployment line 9 by an analysis of reverse press-forming, a reference direction setting step S5 for setting a reference direction for the deployment blank shape 11 related to in-plane anisotropy of a mechanical characteristic and a reference direction transfer step S6 for calculating an angle α formed between the reference direction and each element in the deployment blank shape 11 and transferring the reference direction to each element of the analytical model 7 on the basis of the angle α. |
