在诺威国际博览会上作者见到西德空间与宇航研究院材料研究所展出的这台新型试验机。该试验装置包括有;液压伺服疲劳试验机、电视摄影机、显微镜及专用电子测量电路、数据处理和试验过程控制系统。该设备可测定裂纹的瞬时长度、瞬时疲劳循环次数以及测量次数和测量时间,还可以由打印机进行打印记录。图1幅。 At the Norwich International Expo, the author meets with the new test machine on display at the Institute of Materials Science at the Space and Space Research Institute of the German Institute of Space and Astronautics. The test equipment includes: hydraulic servo fatigue testing machine, television camera, microscope and special electronic measuring circuit, data processing and test process control system. The device can measure the instantaneous length of the crack, the number of instantaneous fatigue cycles and measurement times and measurement time, but also by the printer to print records.
