阅读说明：本技术 用于测量承受离心力的物体的应变的方法和设备 (Method and device for measuring the strain of an object subjected to centrifugal forces ) 是由 A.布施贝克 M.哈特纳格尔 C.希尔 于 2020-05-15 设计创作，主要内容包括：测量承受离心力的转子(2)的应变,方式是,将所述转子(2)安置在旋转试验台(1)的能够与驱动装置相连的容纳件(3)中,触发照相机(4)和作为短时照明单元(6)的短时激光器,并且对所述转子(2)的表面的至少一个区域拍照。将第一图像作为初始状态传输给评估单元(8)。随后加速所述转子(2)并且在至少一个转速下重新触发所述照相机(4)和作为短时照明单元(6)的短时激光器,并且拍摄所述表面的先前被拍照的区域的至少一个另外的图像,将该另外的图像作为测量状态传输给所述评估单元(8)。所述评估单元(8)借助数字的图像相关性计算所述转子(2)在所述表面的被拍照的区域中的应变,其中,所述照相机(4)的图像传感器的曝光时间由从所述短时激光器(6)发出的照明的持续时间确定。(The strain of a rotor (2) subjected to centrifugal force is measured by placing the rotor (2) in a receptacle (3) of a rotating test stand (1) that can be connected to a drive, triggering a camera (4) and a short-time laser as a short-time illumination unit (6), and taking a picture of at least one region of the surface of the rotor (2). The first image is transmitted as an initial state to an evaluation unit (8). Subsequently, the rotor (2) is accelerated and the camera (4) and the short-time laser as a short-time illumination unit (6) are re-triggered at least one rotational speed, and at least one further image of the previously photographed region of the surface is recorded and transmitted as a measurement state to the evaluation unit (8). The evaluation unit (8) calculates the strain of the rotor (2) in the photographed region of the surface by means of digital image correlation, wherein the exposure time of the image sensor of the camera (4) is determined by the duration of the illumination emitted from the short-time laser (6).)
