Study on Measurement System of Tilting Train Based on Math Platform

摘要：

Realizing the real-time measurement of the unbalanced centrifugal acceleration of train through curves is the main task of the measurement system of tilting train.In view of the problems of the existent measurement systems of tilting train,a new measurement method based on math platform is put forward.With three-axis angular rate gyroscopes and accelerometers mounted on the front bogie of train,the angular rates and accelerations of tilting train are measured.With the strict inertial algorithm,the attitudes and positions of train through curves can be accurately obtained.Accordingly the unbalanced centrifugal acceleration can be further computed.What’s more,relative five simplified mathematical models are derived and their errors are analyzed.Simulation and analysis show that this new measurement method based on math platform is effective and feasible.
