摘要： A metal dummy tire which simulates a tire is prepared and used as a master disk. A raised and depressed plate is mounted onto a sidewall surface of the master disk. The raised and depressed plate has a base surface, a raised surface, and a depressed surface. A mask processing section is configured to use mask data in which a given region and the remaining region in each of the base surface, the raised surface and the depressed surface are defined as a valid region and an invalid region, respectively, to extract measurement data of the valid regions from measurement data obtained from the sidewall surface of the master disk. A master data generation section is configured to generate master data representing a surface shape of the master disk, by using the measurement data of the valid regions. A user can check measurement accuracy of a shape inspection device by comparing shape values of the raised and depressed plate with the master data.

摘要： In a rotating machine abnormality detection device, a rotating machine abnormality detection method, and a rotating machine according to the present invention, vibration caused by at least one of first and second rotating bodies is measured, a predetermined feature amount related to a frequency component is obtained based on a frequency spectrum of the measurement data, and determination is made on presence/absence of abnormality based on the obtained predetermined feature amount. On this occasion, when determination is made that abnormality is present, determination whether the determination of abnormality is caused by noise or not is made based on the frequency spectrum, and when determination is made that the determination of abnormality is not caused by the noise, the determined abnormality is ultimately considered as abnormality.

摘要： A sample point extraction unit (323) extracts natural defect candidate portions by using sample points comprising height data for one line obtained by scanning once around the measurement surface of a tire surface. Natural defect candidate portions include natural defect portions and intentional irregularity portions, such as characters and patterns. A differentiation unit (325) stores, in advance, conditions characteristic of the shape of intentional irregularity portions formed on the measurement surface, and from among the natural defect candidate portions, excludes natural defect candidate portions that satisfy those conditions from the natural defect candidate portions. Due to this configuration, intentional irregularity portions are differentiated from natural defect portions.

摘要： A candidate extraction unit (322) executes candidate extraction processing wherein a fixed number of consecutive height data items are extracted from one line of height data using a certain sample point as the starting point, the median for the extracted height data items and the difference therefrom for each extracted height data item are calculated, and sample points with a difference that is at least a height threshold are extracted as singular point candidates. An interpolation unit (323) determines, to be a singular point, a singular point candidate having a number of consecutive repetitions that is less than a width threshold, deletes the height data for the determined singular point, interpolates the deleted height data using height data for sample points which are adjacent to and other than such singular point, and generates shape data for evaluating runout and bulge/dent.
