Vertical track irregularity identification based on a detrending numerical integration algorithm with vehicle acceleration measurements

•A novel algorithm embedding automatic detrending in numerical integration is developed.•Parameter-adaptive VMD is designed for nonstationary acceleration signal decomposition.•Integration errors and nonzero initial conditions are compensated through optimization.•Track irregularities are identified...
