The dynamic response discipline of the sleeper and the selection of the optimal operating parameters were studied for the track dynamic stabilizer under different track conditions. A lateral dynamics model of the dynamic stabilize unit-track system was established. The dynamic model was simulated by MATLAB software combined with numerical integration method. The dynamic response law of the sleeper and the optimal excitation frequency of the dynamic stabilize unit were obtained when the track dynamic stabilizer was under different track conditions. The research results showed that in the same excitation frequency range, with the increase of lateral stiffness and damping of the ballast bed, the average lateral dynamic response of the sleeper became smaller. Meanwhile, the optimal excitation frequency was 31~33 Hz for the track bed conditions studied in this paper.

Key words: multi-body dynamics, dynamic stabilize unit, numerical integration, lateral resistance, track dynamic stabilizer, ballasted track
