Research on the Dynamic Characteristic of the Bogie in Dynamic Track Stabilizer on Working Conditions

With the large-scale speed-up of the railway, the dynamic track stabilizer will play an important role on the track overhauling and railroading of new line in our country. Bogie is one of the major critical components of the dynamic track stabilizer; its vibrating characteristic will affect the vibrating characteristic of the dynamic track stabilizer directly. The method of numerical simulate was used, based on ADAMS simulation, the horizontal exciting forces of the vibration exciter under working conditions were gained. Then the exciting forces were loaded on the bogie, and the dynamic characteristics of the dynamic track stabilizer bogie under the working conditions were obtained on the bases of the ANSYS/LS-DYNA. The analysis results show that the lateral and nod vibrating characteristics of the bogie under working conditions were strong. The analysis results of this paper will provide foundation for the research on the dynamic characteristics and working security of the dynamic track stabilizer.
