【Abstract】 The vibration test data of urban rail transit has enormous amount, and the data processing work is cumbersome. The characteristics of urban rail transit vibration test data and the adaptability of various data processing methods are analyzed, and the data processing method suitable for the vibration test data is put forward. A general program is compiled by using VB and Fortran interactive algorithm. Peak value points of force and displacement test items can be located easily using this software, and statistical analysis is then carried out. The software also has functions of time-frequency conversion with acceleration, 1/3 octave calculation and test data statistical analysis, making data processing more convenient. The proposed vibration test data analysis processing method has solved the all-day train vibration test wheel-rail force, displacement and acceleration peak value automatic extraction problem, elevating the urban rail transit vibration test data processing efficiency.更多还原
