On-line detection of vehicle-mounted ballast bed quality status based on improved Kalman filter

Experimental study on lateral transmission characteristics of vibration wave under the operation of dynamic track stabilizer

“…JADIDIRENDI et al [4] investigated the effect of stabilization on track geometry through statistical tests and YAN et al [5,6] showed through discrete element modelling that the effect of different stabilization frequencies on the track bed varies and that a stabilization frequency of 30 Hz is the optimum frequency for simulation analysis. CHEN et al [7] considered the track as a dynamic system, the stabilizer applied transverse excitation to the rail, and estimated the transverse vibration displacement of the rail by detecting the acceleration signal of the stabilizer, and proposed to use the transverse displacement of the rail as a new evaluation index of the quality state of the rail bed.…”
