| Abstract: | For the disperse impetus dynamoelectric locomotive groups (DIDLG), an experimental study on the dynamic stress-strain impacts of a roadbed-culvert transition section of Shan-Sui multiple tests section in Qin-Shen passenger transport special railway line was conducted by using the method of high capability multicenter parallel data collecting and analyzing system, BY-1 dynamic-static stress sensor, etc.. It is obtained, that the dynamic stress-strain caused by DIDLG is steady comparatively, which is very advantageous for the high speed run of train; In the meantime, the dynamic stress-strain characteristics and the change trend in the direction of railway line of roadbed-culvert transition section are analyzed. |
