| Abstract: | According to the track geometry data collected by track recording vehicles from Shanghai urban rail tran-sitt,he characteristic of track irregularity is analyzed.Firstlyt,he elimination methods of abnormal value and nonlin-ear trend are given and used in the data preprocessing of track irregularities on urban rail transit based on the change rate of track irregularity and the method of empirical mode decomposition.Secondly,power spectral density is calcu-lated with Matlab program,and compared with US class ... |
