To provide a calculation method that enables a heating plan for approximating a plate to an intended shape to be calculated in a short period of time.

A calculation method according to the present invention is a calculation method of a heating plan for deforming a plate by heating, the calculation method including: a Bayesian optimization step of performing a Bayesian optimization by inputting a training data group including a plurality of combinations of heating conditions that include a heating shape having been set at an arbitrary location of an analysis model for an original shape being a shape of the plate and a shape that has been calculated based on the heating conditions and determining a heating conditions candidate; and a finite element analysis step of converting the heating conditions candidate into strain data and performing a structural analysis based on a finite element method by inputting the strain data to output a shape candidate.

A surgical clip for a surgical clip applicator includes at least one pair of clip arms. Each clip arm has a distal end and a proximal end. The two clip arms are connected to each other at the proximal ends of the clip arms and form a clip throat. A tangent angle between a tangent to a neutral fiber of a clip arm and a perpendicular to a longitudinal axis of the clip increases over the entire length of the clip arm substantially continuously.

In certain embodiments described herein, a heated line forming system includes a heating coil system configured to produce a heated line on a surface of a metal part. The heated line forming system also includes an air knife cooling system configured to maintain a dry area for the heated line, and to direct a coolant (e.g., cooling water, liquified gases such as liquid argon, solidified gases such as carbon dioxide snow, and so forth) around the heated line via a spray mechanism such that the coolant does not flow or splash into the heated line on the metal part. In certain embodiments, the heated line forming system includes multiple induction coils arranged along a line and spaced a short distance apart, but which, when operated simultaneously together, form a heated line on a surface of a metal part.

A method of manufacturing a washer capable of improving a material yield is provided. The method includes: a preparation step of preparing a longitudinal member which includes an upper corrugated portion and a lower corrugated portion including crest portions formed on at least one of an upper surface and a lower surface and valley portions continuous to the crest portions in the right-left direction; and a deformation step of deforming the longitudinal member such that the upper surface and the lower surface are arcuate as viewed in the direction from the front to the rear.

An automated method for straightening/correcting deformations made to panels when welded to metallic structural components is disclosed. In the train industry, when an aluminum component, such as a vehicle's exterior shell, is welded to hidden structural parts, deformations thereon may occur. Such deformations need to be subsequently corrected, and the present method uses robots and optical measuring of the deformed surfaces to conduct a straightening thereof. The method includes four main steps. First, the deformed surface is scanned with an optical sensor to make physical measures/characterizations thereof. Second, the gathered data are compared with the desired resultant by a software. Third, once the comparison is done, the software performs an analysis to select the proper parameters to be used in the straightening method that will be applied at each area requiring straightening. Finally, a robot executes the operations specified by the software to perform the straightening process.
