発明の名称 (英語) METHOD AND DEVICE FOR ANALYZING LAMINATION-SHAPED ARTICLE, AND METHOD AND DEVICE FOR MANUFACTURING LAMINATION-SHAPED ARTICLE NEW
発明の概要(英語) A displacement/stress calculation unit (220) is configured to calculate residual stress and deformation by executing a thermo-elasto-plastic analysis by means of an idealized explicit method FEM. The magnitude of a temperature increment is set to a value greater than that of a temperature increment used in a thermo-elasto-plastic analysis by means of a static implicit method FEM. Heating is performed for each of a plurality of blocks according to a heating pattern in which blocks that are not adjacent to each other are simultaneously heated. The heating performed for each of the blocks is performed using a planar heat source having a heat input amount that is adjusted with respect to a heat input amount used for heating by a movable heat source.
従来技術、競合技術の概要(英語) BACKGROUND ART
While to solidify the molten material generated by the deposits has attracted attention in recent years a laminated object. For example, metal powder of the like is irradiated with a laser or electron beam melting the metal powder, by solidifying the modeling object in the desired form, the printer has been known a so-called metal 3D. Patent No. 2620353, such as a metal powder layer is irradiated with a laser beam at a predetermined position of the corresponding portions of the powder is sintered and the sintered layer is formed, such a sintered layer are sequentially formed on the stacked three-dimensional shape by a method of generating an object has been disclosed (see Patent Document 1).
In addition, the lamination or powder resin is used, the molten resin melted by arc discharge while depositing the metal and the like are also known the lamination.
