%X DH5923 dynamic signal analysis system was adopted to measure the stress in rescue device equipped on a C80 Locomotive. The test recorded multi-channel dynamic signals in a long time period without interruption based on computer interface (1394). Computer recorded the strain profile when locomotive moved forward and backward with different speeds. Strain peaks of six test points during different time periods were also acquired in experiments. Real time temperature curves of wheel shaft were recorded during whole test. Results show that temperature and strain of test point on railroad switches present dramatic changes. The highest temperature of wheel shaft in whole test process was also obtained. Experiments show that the performance of rescue device meets the design requirements. The experiment data are also helpful for further improvement of rescue device.
