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.
