    • In the process of target stamping for fracture judgment, an acquisition unit acquires, as target data for fracture judgment, strain of a target die to be measured over the duration from the start time of stamping measured by strain measuring units to the finishing time of stamping, and also acquires production conditions typically by measurement. An extraction unit extracts the reference data, which gives the minimum total of differences between the production conditions of the reference data and the production conditions of the target data for fracture judgment, as the comparative data. A judging unit compares strain in the comparative data extracted by the extraction unit and strain in the target data for fracture judgment, and judges occurrence of a crack in a stamped product, if the maximum value of the difference is not smaller than a predetermined value.
    • 在用于断裂判断的目标冲压的过程中,采集单元从应变测量单元测量的冲压开始时间到冲压结束时间获取作为断裂判断的目标数据的待测量目标模具的应变 ,并且通常通过测量获得生产条件。 提取单元提取参考数据,其给出参考数据的生产条件与用于断裂判断的目标数据的生产条件之间的最小差异总和作为比较数据。 评估单元比较由提取单元提取的比较数据中的应变和用于断裂判断的目标数据中的应变,并且如果差的最大值不小于预定值,则判断冲压产品中的裂纹发生。

    • A structure including a structural member (1) configured like a frame with four sides is disclosed. A closed cross-section structural member (4) serving as a reinforcing material is provided in a crossing corner (2) of the structural member (1). The closed cross-section structural member (4) includes two horizontal portions (5) separated from each other in a thickness direction of the structural member (1) and extending in an in-plane direction of the structural member (1) and two vertical portions (6) one of which connects first ends of the two horizontal portions (5) together and the other of which connects second ends of the two horizontal portions (5) together. The closed cross-section structural member (4) includes a first opening (7) formed therein facing an inner-peripheral flat surface (1a) of the structural member (1) and a second opening (8) formed therein facing inside of the structural member (1). The height h0 of the closed cross-section structural member (4) is substantially the same as the thickness H of the structural member (1). The opening edge of the first opening (7) is entirely joined to the inner-peripheral flat surface (1a) of the structural member (1). A flattening that is the ratio of the maximum width H of the second opening (8) to a height h0 of the closed cross-section structural member (4) is greater than 1.0 and not greater than 3.0.
