Detecting the Characteristics of Long-Wave Irregularity of Maglevrailway Based on Strap-Down Inertial System

摘要：

In this paper, a new approach has been provided to detect the maglev track irregularity which is the strap-down inertial system. In this system, the space attitude matrix has been programmed to realize the conversion from the measurement reference frame to the inertial reference frame. Basing on the maglev railway testing with Time-Frequency Analysis, the author has analyzed track irregularity long-wave signals, achieved the orientation about the track irregularity long-wave signals and used the WT (wavelet transform) to detect the maglev railway testing data, and to estimate and recompose the track irregularity long-wave signals.
