The kinematic posture of the bogie within comprehensive inspection trains exerts a profound influence on the precision of the measurement systems. This study develops an advanced posture calculation algorithm by integrating data from multiple accelerometers. Rigorous analytical evaluations of the bogie’s central motion posture within the comprehensive inspection train delineate a pronounced escalation in the magnitude of this motion posture concomitant with increased velocities, thereby unveiling a robust correlation in posture outcomes at consistent speeds. Confronting the limitations inherent in the multi-accelerometer amalgamation approach, particularly its diminished sensitivity to posture angle variations precipitated by track geometry anomalies, this research introduces an avant-garde posture compensation paradigm. This paradigm has been corroborated through meticulously constructed experimental models. The rectified outcomes for lateral and vertical displacements, and for roll and nodding angles in posture computation manifest peak errors of 0.09, 0.01, 0.02, and 0.03, respectively, alongside absolute errors amounting to 0.17, 0.04, 0.08, and 0.06, respectively. These empirical findings provide robust substantiation for the analytical dissection of measurement systems accuracy aboard comprehensive inspection trains under diverse operational scenarios. Such revelations bear significant connotations for augmenting the precision and reliability of contemporary railway inspection methodologies.
