The dynamic properties of three types of fasteners （WJ-7B， WJ-8， and Vossloh 300）commonly used on Chinese high-speed railways are studied in this paper. An experimental method and a theoretical model for determining and expressing the dynamic stiffness of the fastener systems are proposed， taking the broad frequency-band features of wheel-rail excitation into account. According to the hammer test method， the dynamic responses of the three assembled fasteners were obtained for a frequency range of 100 to 800 Hz and for temperature ranging from -50 to 10°C. Results show that the dynamic stiffness of WJ-8 and Vossloh 300 is sensitive to temperature， but less affected by frequency. The dynamic stiffness of WJ-8 at -50 °C can be as much as 23 times higher than that at 10 °C. The dynamic stiffness of Vossloh 300 at -50 °C is up to 67 times higher than at 10 °C. The dynamic stiffness of WJ-7B is more affected by frequency. The dynamic stiffness at 800 Hz is 12~17 times higher than that at 100 Hz. The damping ratios of WJ-8 and Vossloh 300 increase with decreasing ambient temperature， reaching a maximum at the glass transition temperature. The results presented in this paper may provide a reference for the design and selection of fasteners for railways working in extremely low temperature environments.
