Dynamic stringer forming system

摘要

A method and apparatus for bending an elongate member. A plastic force may be applied to the elongate member. The plastic force may be configured to cause the elongate member to bend with a plastic deformation. The plastic force may be reduced to an elastic force that is applied to the elongate member after the plastic force causes the elongate member to bend with the plastic deformation.

1. A method for bending an elongate member, the method comprising:
applying a first elastic force to the elongate member before the elongate member is bent by applying a plastic force to the elongate member; identifying an amount of deflection of the elongate member while applying the first elastic force; applying the plastic force to the elongate member after identifying the amount of deflection, in which the plastic force is configured to cause the elongate member to bend with a plastic deformation; reducing the plastic force after the plastic force causes the elongate member to bend with the plastic deformation; applying a second elastic force to the elongate member after applying the plastic force to the elongate member; identifying a bend of the elongate member while the second elastic force is applied to the elongate member; and repeating the steps of applying the plastic force to the elongate member in which the plastic force is configured to cause the elongate member to bend with the plastic deformation, reducing the plastic force after the plastic force causes the elongate member to bend with the plastic deformation, applying the second elastic force to the elongate member after applying the plastic force to the elongate member, and identifying the bend of the elongate member while the second elastic force is applied to the elongate member until the bend of the elongate member is a desired bend for the elongate member.
